+<section name="Configuration Directives">
+<p>
+Most of the directives are allowed once in the global part of the Apache httpd
+configuration and once in every &lt;VirtualHost&gt; elements. Exceptions from this rule are
+explicitly listed in the table below.
+</p>
+<p>
+Most values are inherited from the main server to the virtual hosts.
+Since version 1.2.20 they can be overwritten in the virtual hosts.
+Exceptions from this rule are again explicitly listed in the table below.
+See especially JkMountCopy.
+</p>
+<warn>
+Warning: If Apache httpd and Tomcat are configured to serve content from
+the same filing system location then care must be taken to ensure that httpd is
+not able to serve inappropriate content such as the contents of the WEB-INF
+directory or JSP source code.
+</warn>
+<p>
+This could occur if the httpd DocumentRoot
+overlaps with a Tomcat Host's appBase or the docBase of any Context. It could
+also occur when using the httpd Alias directive with a Tomcat Host's appBase or
+the docBase of any Context.
+</p>
+<p>
+Here are the all directives supported by Apache:
+</p>
+<attributes name="Directive">
+<attribute name="JkWorkersFile" required="false"><p>
+The name of a worker file for the Tomcat servlet containers.
+<br/>
+This directive is only allowed once. It must be put into
+the global part of the configuration.
+<br/>
+If you don't use the JkWorkerProperty directives, then you must
+define your workers with a valid JkWorkersFile. There is no default
+value.
+</p></attribute>
+<attribute name="JkWorkerProperty" required="false"><p>
+Enables setting worker properties inside Apache configuration file.
+The syntax is the same as in the JkWorkersFile (usually workers.properties).
+Simply prefix each line with "JkWorkerProperty" to put it directly into
+the Apache httpd config files.
+<br/>
+This directive is allowed multiple times.
+It must be put into the global part of the configuration.
+<br/>
+If you don't use the JkWorkerProperty directives, then you must
+define your workers with a valid JkWorkersFile. There is no default
+value.
+<br/>
+This directive is available in jk1.2.7 version and later.
+</p></attribute>
+<attribute name="JkShmFile" required="false"><p>
+Shared memory file name. Used only on unix platforms.
+The shm file is used by balancer and status workers.
+<br/>
+This directive is only allowed once. It must be put into
+the global part of the configuration.
+<br/>
+The default value is logs/jk-runtime-status.
+It is highly recommended that the shm file be placed on a local
+drive and not an NFS share.
+</p>
+<p>
+The shared memory contains configuration and runtime information for load balancer
+workers and their members. It is need in order that all apache children
+<ul>
+<li>share the same status information for load balancing members (OK, ERROR, ...),</li>
+<li>share the information about load taken by the individual workers,</li>
+<li>share the information for the parts of the configuration, which are changeable
+during runtime by status workers.</li>
+</ul>
+</p>
+</attribute>
+<attribute name="JkShmSize" required="false"><p>
+Size of the shared memory file name.
+<br/>
+This directive is only allowed once. It must be put into
+the global part of the configuration.
+<br/>
+The default value depends on the platform. It is usually less than 64KB.
+</p></attribute>
+<p>Starting with version 1.2.27 the size of the shared memory is determined
+automatically, even for large numbers of workers. This attribute is not
+needed any longer.</p>
+<attribute name="JkMountFile" required="false"><p>
+File containing multiple mappings from a context to a Tomcat worker.
+It is usually called uriworkermap.properties.
+<br/>
+For inheritance rules, see: JkMountCopy.
+<br/>
+There is no default value.
+</p></attribute>
+<attribute name="JkMountFileReload" required="false"><p>
+This directive configures the reload check interval in seconds.
+The JkMountFile is checked periodically for changes.
+A changed file gets reloaded automatically. If you set
+this directive to "0", reload checking is turned off.
+<br/>
+The default value is 60 seconds.
+<br/>
+This directive has been added in version 1.2.20 of mod_jk.
+</p></attribute>
+<attribute name="JkMount" required="false"><p>
+A mount point from a context to a Tomcat worker.
+<br/>
+This directive is allowed multiple times.
+It is allowed in the global configuration and in VirtualHost.
+You can also use it inside Location with a different syntax.
+Inside Location, one omits the first argument (path),
+which gets inherited from the Location.
+<br/>
+By default JkMount entries are not inherited from the global
+server to other VirtualHosts or between VirtualHosts.
+For the complete inheritance rules, see: JkMountCopy.
+</p></attribute>
+<attribute name="JkUnMount" required="false"><p>
+An exclusion mount point from a context to a Tomcat worker.
+All exclusion mounts are checked after mapping a request
+to a tomcat worker. If the request maps also to an exclusion,
+it will not be forwarded to tomcat, and instead be served locally.
+<br/>
+This directive is allowed multiple times.
+It is allowed in the global configuration and in VirtualHost.
+You can also use it inside Location with a different syntax.
+Inside Location, one omits the first argument (path),
+which gets inherited from the Location.
+For inheritance rules, see: JkMountCopy.
+<br/>
+This directive is available in jk1.2.7 version and later.
+</p></attribute>
+<attribute name="JkAutoAlias" required="false"><p>
+Automatically Alias webapp context directories into the Apache
+document space.
+<br/>
+Care should be taken to ensure that only static content is served via httpd as a
+result of using this directive. Any static content served by httpd will bypass any
+security constraints defined in the application's web.xml.
+<br/>
+For inheritance rules, see: JkMountCopy.
+<br/>
+There is no default value.
+</p></attribute>
+<attribute name="JkMountCopy" required="false"><p>
+If this directive is set to "On" in some virtual server,
+the mounts from the global server will be copied to this
+virtual server, more precisely all mounts defined by JkMount
+or JkUnMount. The Mounts defined by JkMountFile and JkAutoAlias
+will only be inherited, if the VirtualHost does not define
+it's own JkMountFile or JkAutoAlias.
+<br/>
+If you want all vhost to inherit mounts from the main server,
+you can set JkMountCopy to 'All' in the main server.
+<br/>
+This directive is only allowed inside VirtualHost (with value "On")
+and in the global server (with value "All").
+<br/>
+The default is Off, so no mounts will be inherited from the global
+server to any VirtualHost.
+<br/>
+Starting with version 1.2.26 you can also set it to "All" in the
+global virtual server. This will switch the default to On.
+</p></attribute>
+<attribute name="JkWorkerIndicator" required="false"><p>
+Name of the Apache environment variable that can be used to set worker names
+in combination with SetHandler jakarta-servlet.
+<br/>
+This directive is only allowed once per virtual server.
+It is allowed in the global configuration and in VirtualHost.
+<br/>
+The default value is JK_WORKER_NAME.
+</p></attribute>
+<attribute name="JkWatchdogInterval" required="false"><p>
+This directive configures the watchdog thread interval in seconds.
+The workers are maintained periodically by a background thread
+running periodically every watchdog_interval seconds. Worker maintenance
+checks for idle connections, corrects load status and is able
+to detect backend health status.
+<br/>
+The maintenance only happens, if since the last maintenance at
+least <a href="workers.html"><code>worker.maintain</code></a>
+seconds have passed. So setting the JkWatchdogInterval
+much smaller than <code>worker.maintain</code> is not useful.
+<br/>
+The default value is 0 seconds, meaning the watchdog thread
+will not be created, and the maintenance is done in combination
+with normal requests instead.
+<br/>
+This directive is only allowed once. It must be put into
+the global part of the configuration.
+<br/>
+This directive has been added in version 1.2.27 of mod_jk.
+It is available only for httpd 2.x and above using APR libraries
+including thread support.
+</p></attribute>
+<attribute name="JkLogFile" required="false"><p>
+Full or server relative path to the Tomcat Connector module log file.
+It will also work with pipe, by using a value of the form "| ...".
+<br/>
+The default value is logs/mod_jk.log.
+<br/>
+Pipes are supported for Apache 1.3 only since version 1.2.16.
+The default value exists only since version 1.2.20.
+</p></attribute>
+<attribute name="JkLogLevel" required="false"><p>
+The Tomcat Connector module log level, can be debug, info, warn
+error or trace.
+<br/>
+The default value is info.
+</p></attribute>
+<attribute name="JkLogStampFormat" required="false"><p>
+The Tomcat Connector module <b>date</b> log format, using an
+extended strftime syntax.
+This format will be used for the time stamps in the JkLogFile.
+The maximum length of the format is 63 characters.
+<br/>
+Starting with version 1.2.24 of mod_jk you can also use %Q
+for adding milliseconds to the log and %q for microseconds.
+These conversion specifiers are an extension to strftime.
+They will only work on platforms with a gettimeofday() function.
+You can use %Q and %q only once in the pattern and also not both
+together in the same pattern.
+<br/>
+The default value is "[%a %b %d %H:%M:%S %Y] " and beginning
+with version 1.2.24 on platforms with a gettimeofday()
+function it is "[%a %b %d %H:%M:%S.%Q %Y] ".
+</p></attribute>
+<attribute name="JkRequestLogFormat" required="false"><p>
+Request log format string. See detailed description below.
+<br/>
+There is no default value. Without defining a value, the request logging
+is turned off.
+</p></attribute>
+<attribute name="JkExtractSSL" required="false"><p>
+Turns on SSL processing and information gathering by mod_jk
+<br/>
+The default value is On.
+<br/>
+In order to make SSL data available for mod_jk in Apache, you need to
+set <code>SSLOptions +StdEnvVars</code>. For the certificate information you also need
+to add <code>SSLOptions +ExportCertData</code>.
+</p>
+<p>
+ Specifically, mod_jk will export the following environment variables from
+ Apache httpd to Tomcat under these request attributes as per the
+ Servlet Specification 3.0, section 3.8:
+</p>
+<table>
+ <tr><th>Env Var</th><th>Request Attribute Name</th><th>Type</th><th>Example</th></tr>
+ <tr>
+ <td>SSL_CIPHER<br/>(or <code>JkKEYSIZEIndicator</code>)</td>
+ <td>javax.servlet.request.cipher_suite</td>
+ <td>java.lang.String</td>
+ <td>DHE-RSA-AES256-SHA</td>
+ </tr>
+ <tr>
+ <td>SSL_CIPHER_USEKEYSIZE<br/>(or <code>JkKEYSIZEIndicator</code>)</td>
+ <td>javax.servlet.request.key_size</td>
+ <td>java.lang.Integer</td>
+ <td>256</td>
+ </tr>
+ <tr>
+ <td>SSL_SESSION_ID<br/>(or <code>JkSESSIONIndicator</code>)</td>

+ <td>java.security.X509Certificate[]</td>
+ <td>(A chain of certs in ascending order of trust, the first one being
+ ths client's certificate, the second being the signer of that
+ certificate, and so on)</td>
+ </tr>
+</table>
+<p>
+ For all other SSL-related variables, use <code>JkEnvVar</code> for each
+ variable you want. Please note that, like <code>JkEnvVar</code>, these
+ variables are available from the request <i><b>attributes</b></i>, not as
+ environment variables or as request headers.

+<section name="Configuration Directives Types">
+<p>
+We'll discuss here the mod_jk directive types.
+</p>
+
+<subsection name="Define workers">
+<p>
+<b>JkWorkersFile</b> specify the location where mod_jk will find the workers definitions.
+Take a look at <a href="workers.html">Workers documentation</a> for detailed description.
+
+<source>
+ JkWorkersFile /etc/httpd/conf/workers.properties
+</source>

+<b>JkLogFile</b> specify the location where mod_jk is going to place its log file.
+</p>
+
+<source>
+ JkLogFile /var/log/httpd/mod_jk.log
+</source>
+
+<p>
+Since JK 1.2.3 for Apache 2.x and JK 1.2.16 for Apache 1.3 this can also
+be used for piped logging:
+</p>
+
+<source>
+ JkLogFile "|/usr/bin/rotatelogs /var/log/httpd/mod_jk.log 86400"
+</source>
+
+<p>
+<b>JkLogLevel</b>
+set the log level between :
+</p>
+
+<ul>
+<li>
+<b>info</b> log will contain standard mod_jk activity (default).
+</li>
+<li>
+<b>warn</b> log will contain non fatal error reports.
+</li>
+<li>
+<b>error</b> log will contain also error reports.
+</li>
+<li>
+<b>debug</b> log will contain all information on mod_jk activity
+</li>
+<li>
+<b>trace</b> log will contain all tracing information on mod_jk activity
+</li>
+</ul>
+
+<source>
+ JkLogLevel info
+</source>
+
+<p>
+<code>info</code> should be your default selection for normal operations.
+<br/>
+<br/>
+</p>
+
+<p>
+<b>JkLogStampFormat</b> will configure the date/time format found on mod_jk log file.
+Using the strftime() format string it's set by<br />

+Request logging is configured and enabled on a per virtual host basis.
+To enable request logging for a virtual host just add a JkRequestLogFormat config.
+The syntax of the format string is similar to the Apache LogFormat command,
+here is a list of the available request log format options:
+</p>
+
+<p>

+<subsection name="Forwarding">
+<p>
+The directive JkOptions allow you to set many forwarding options which will enable (+)
+or disable (-) following option. Without any leading signs, options will be enabled.
+<br/>
+<br/>
+</p>
+
+<p>
+The four following options <b>+ForwardURIxxx</b> are mutually exclusive.
+Exactly one of them is required, a negative sign prefix is not allowed with them.
+The default value is "ForwardURIProxy" since version 1.2.24.
+It was "ForwardURICompatUnparsed" in version 1.2.23 and
+"ForwardURICompat" until version 1.2.22.
+You can turn the default off by switching on one of the other two options.
+You should leave this at it's default value, unless you have a very good
+reason to change it.
+<br/>
+<br/>
+</p>
+
+<p>
+All options are inherited from the global server to virtual hosts.
+Options that support enabling (plus options) and disabling (minus options),
+are inherited in the following way:
+<br/>
+<br/>
+options(vhost) = plus_options(global) - minus_options(global) + plus_options(vhost) - minus_options(vhost)
+<br/>
+<br/>
+</p>
+
+<p>
+Using JkOptions <b>ForwardURIProxy</b>, the forwarded URI
+will be partially reencoded after processing inside Apache httpd and
+before forwarding to Tomcat. This will be compatible with local
+URL manipulation by mod_rewrite and with URL encoded session ids.
+
+<source>
+ JkOptions +ForwardURIProxy
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+Using JkOptions <b>ForwardURICompatUnparsed</b>, the forwarded URI
+will be unparsed. It's spec compliant and secure.
+It will always forward the original request URI, so rewriting
+URIs with mod_rewrite and then forwarding the rewritten URI
+will not work.
+
+<source>
+ JkOptions +ForwardURICompatUnparsed
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+Using JkOptions <b>ForwardURICompat</b>, the forwarded URI will
+be decoded by Apache httpd. Encoded characters will be decoded and
+explicit path components like ".." will already be resolved.
+This is less spec compliant and is <b>not safe</b> if you are using
+prefix JkMount. This option will allow to rewrite URIs with
+mod_rewrite before forwarding.
+
+<source>
+ JkOptions +ForwardURICompat
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+Using JkOptions <b>ForwardURIEscaped</b>, the forwarded URI will
+be the encoded form of the URI used by ForwardURICompat.
+Explicit path components like ".." will already be resolved.
+This will not work in combination with URL encoded session IDs,
+but it will allow to rewrite URIs with mod_rewrite before forwarding.
+
+<source>
+ JkOptions +ForwardURIEscaped
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>RejectUnsafeURI</b> will block all
+URLs, which contain percent signs '%' or backslashes '\'
+after decoding.
+<br/>
+<br/>
+</p>
+<p>
+Most web apps do not use such URLs. Using the option RejectUnsafeURI, you
+can block several well known URL encoding attacks. By default, this option
+is not set.
+</p>
+<p>
+You can also realise such a check with mod_rewrite, which is more powerful
+but also slightly more complicated.
+
+<source>
+ JkOptions +RejectUnsafeURI
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>ForwardDirectories</b> is used in conjunction with <b>DirectoryIndex</b>
+directive of Apache web server. As such mod_dir should be available to Apache,
+statically or dynamically (DSO)
+<br/>
+<br/>
+</p>
+
+<p>
+When DirectoryIndex is configured, Apache will create sub-requests for
+each of the local-url's specified in the directive, to determine if there is a
+local file that matches (this is done by stat-ing the file).
+</p>
+
+<p>
+If ForwardDirectories is set to false (default) and Apache doesn't find any
+files that match, Apache will serve the content of the directory (if directive
+Options specifies Indexes for that directory) or a <code>403 Forbidden</code> response (if
+directive Options doesn't specify Indexes for that directory).
+</p>
+
+<p>
+If ForwardDirectories is set to true and Apache doesn't find any files that
+match, the request will be forwarded to Tomcat for resolution. This is used in
+cases when Apache cannot see the index files on the file system for various
+reasons: Tomcat is running on a different machine, the JSP file has been
+precompiled etc.
+</p>
+
+<p>Note that locally visible files will take precedence over the
+ones visible only to Tomcat (i.e. if Apache can see the file, that's the one
+that's going to get served). This is important if there is more then one type of
+file that Tomcat normally serves - for instance Velocity pages and JSP pages.
+
+<source>
+ JkOptions +ForwardDirectories
+</source>
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>ForwardLocalAddress</b>, you ask mod_jk to send the local address,
+of the Apache web server instead remote client address. This can be used by
+Tomcat remote address valve for allowing connections only from registered Apache
+web servers.
+
+<source>
+ JkOptions +ForwardLocalAddress
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>FlushPackets</b>, you ask mod_jk to flush Apache's connection
+buffer after each AJP packet chunk received from Tomcat. This option can have
+a strong performance penalty for Apache and Tomcat as writes are performed
+more often than would normally be required (ie: at the end of each
+response).
+
+<source>
+ JkOptions +FlushPackets
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>FlushHeader</b>, you ask mod_jk to flush Apache's connection
+buffer after the response headers have been received from Tomcat.
+
+<source>
+ JkOptions +FlushHeader
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>DisableReuse</b>, you ask mod_jk to close connections immediately
+after their use. Normally mod_jk uses persistent connections and pools idle
+connections to reuse them, when new requests have to be sent to Tomcat.
+</p>
+
+<p>
+Using this option will have a strong performance penalty for Apache and Tomcat.
+Use this only as a last resort in case of unfixable network problems.
+If a firewall between Apache and Tomcat silently kills idle connections,
+try to use the worker attribute socket_keepalive in combination with an appropriate
+TCP keepalive value in your OS.
+
+<source>
+ JkOptions +DisableReuse
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>ForwardKeySize</b>, you ask mod_jk, when using ajp13, to forward also the SSL Key Size as
+required by Servlet API 2.3.
+This flag shouldn't be set when servlet engine is Tomcat 3.2.x (on by default).
+
+<source>
+ JkOptions +ForwardKeySize
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+JkOptions <b>ForwardSSLCertChain</b>, you ask mod_jk, when using ajp13,
+to forward SSL certificate chain (off by default).
+Mod_jk only passes the <code>SSL_CLIENT_CERT</code> to the AJP connector. This is not a
+problem with self-signed certificates or certificates directly signed by the
+root CA certificate. However, there's a large number of certificates signed by
+an intermediate CA certificate, where this is a significant problem: A servlet
+will not have the possibility to validate the client certificate on its own. The
+bug would be fixed by passing on the <code>SSL_CLIENT_CERT_CHAIN</code> to Tomcat via the AJP connector.
+<br/>
+This directive exists only since version 1.2.22.
+<source>
+ JkOptions +ForwardSSLCertChain
+</source>
+
+<br/>
+<br/>
+</p>
+
+<p>
+The directive <b>JkEnvVar</b> allows you to forward environment variables
+from Apache server to Tomcat engine.
+You can add a default value as a second parameter to the directive.
+If the default value is not given explicitly, the variable
+will only be send, if it is set during runtime.
+<br/>
+The variables can be retrieved on the Tomcat side as request attributes
+via request.getAttribute(attributeName).
+Note that the variables send via JkEnvVar will not be listed
+in request.getAttributeNames().
+<br/>
+<br/>
+The variables are inherited from the global server to virtual hosts.

+
+</subsection>
+
+<subsection name="Assigning URLs to Tomcat">
+<p>
+If you have created a custom or local version of mod_jk.conf-local as noted above,
+you can change settings such as the workers or URL prefix.
+</p>
+<p>
+<b>JkMount</b> directive assign specific URLs to Tomcat.
+In general the structure of a JkMount directive is:
+</p>
+
+<source>
+ JkMount [URL prefix] [Worker name]
+</source>
+
+<source>
+ # send all requests ending in .jsp to worker1
+ JkMount /*.jsp worker1
+ # send all requests ending /servlet to worker1
+ JkMount /*/servlet/ worker1
+ # send all requests jsp requests to files located in /otherworker will go worker2
+ JkMount /otherworker/*.jsp worker2
+</source>
+
+<p>
+You can use the JkMount directive at the top level or inside &lt;VirtualHost&gt;
+sections of your httpd.conf file.
+</p>
+<p><b>JkUnMount</b> directive acts as an opposite to JkMount and blocks access
+to a particular URL. The purpose is to be able to filter out the particular content
+types from mounted context. The following example mounts /servlet/*
+context, but all .gif files that belongs to that context are not served.
+</p>
+<source>
+ # send all requests ending with /servlet to worker1
+ JkMount /servlet/* worker1
+ # do not send requests ending with .gif to worker1
+ JkUnMount /servlet/*.gif worker1
+</source>
+<p>
+JkUnMount takes precedence over JkMount directives, meaning that the JK
+will first try to mount and then checks, if there is an exclusion defined by a
+JkUnMount. A JkUnMount overrides a JkMount only, if the worker names in the
+JkMount and in the JkUnMount are the same.
+</p>
+<p>
+The following example will block all .gif files although there is a JkMount for them:
+</p>
+<source>
+ # do not send requests ending with .gif to worker1
+ JkUnMount /*.gif worker1
+ # The .gif files will not be mounted cause JkUnMount takes
+ # precedence over JkMount directive
+ JkMount /servlet/*.gif worker1
+</source>
+<p>
+Starting with version 1.2.26 of JK you can apply a JkUnMount to any worker,
+by using the star character '*' as the worker name in the JkUnMount.
+More complex patterns in JkUnMount worker names are not allowed.
+</p>
+<source>
+ # Mapping the webapps myapp1 and myapp2:
+ /myapp1/*=worker1
+ /myapp2/*=worker2
+ # Exclude the all subdirectories static for all workers:
+ !/*/static/*=*
+ # Exclude some suffixes for all workers:
+ !*.html=*
+</source>
+<p>
+<b>JkAutoAlias</b> directive automatically <b>Alias</b> webapp context directories into
+the Apache document space. It enables Apache to serve a static context while Tomcat
+serving dynamic context. This directive is used for convenience so that you don't
+have to put an apache Alias directive for each application directory inside Tomcat's
+webapp directory. For security reasons is is strongly recommended that JkMount
+is used to pass all requests to Tomcat by default and JkUnMount is used to
+explicitly exclude static content to be served by httpd. It should also be noted
+that content served by httpd will bypass any security constraints defined in the
+application's web.xml.
+</p>
+<source>
+ # enter the full path to the tomcat webapps directory
+ JkAutoAlias /opt/tomtact/webapps
+</source>
+<p>The following example shows how to serve a dynamic context by
+Tomcat and static using Apache. The webapps directory has to
+be accessible by apache.</p>
+
+<source>
+ # enter the full path to the tomcat webapps directory
+ JkAutoAlias /opt/tomtact/webapps
+
+ # Mount 'servlets-examples' directory. It's physical location
+ # is assumed to be in the /opt/tomtact/webapps/servlets-examples
+ # ajp13w is a worker defined in the workers.properties
+ JkMount /servlets-examples/* ajp13w
+
+ # Unmount desired static content from servlets-examples webapp.
+ # This content will be served by the httpd directly.
+ JkUnMount /servlets-examples/*.gif ajp13w
+ JkUnMount /servlets-examples/*.jpg ajp13w
+</source>
+<p>Note that you can have a single JkAutoAlias directive per virtual
+host inside your httpd.conf
+</p>
+<p>
+<b>JkWorkerProperty</b> is a new directive available from JK 1.2.7
+version. It is a convenient method for setting directives that are
+usually set inside <b>workers.propeties</b> file. The parameter for
+that directive is raw line from workers.properties file.
+</p>
+<source>
+ # Just like workers.properties but exact line is prefixed
+ # with JkWorkerProperty
+
+ # Minimal jk configuration
+ JkWorkerProperty worker.list=ajp13w
+ JkWorkerProperty worker.ajp13w.type=ajp13
+ JkWorkerProperty worker.ajp13w.host=localhost
+ JkWorkerProperty worker.ajp13w.port=8009
+</source>
+<p>
+<b>JkMountFile</b> is a new directive available from JK 1.2.9
+version. It is used for dynamic updates of mount points at runtime.
+When the mount file is changed, JK will reload it's content.
+</p>
+<source>
+ # Load mount points
+
+ JkMountFile conf/uriworkermap.properties
+</source>
+<p>If the mount point uri starts with an exclamation mark '!'
+it defines an exclusion in the same way JkUnMount does.
+If the mount point uri starts with minus sign '-'
+the mount point will only be disabled. A disabled mount can be reenabled
+by deleting the minus sign and waiting for the JkMountFile to reload.
+An exclusion can be disabled by prefixing it with a minus sign.
+</p>
+<source>
+ # Sample uriworkermap.properties file
+
+ /servlets-examples/*=ajp13w
+ # Do not map .jpeg files
+ !/servlets-examples/*.jpeg=ajp13w
+ # Make jsp examples initially disabled
+ -/jsp-examples/*=ajp13w
+</source>
+<p>At run time you can change the content of this file. For example
+removing minus signs will enable the previously disabled uri mappings.
+You can add any number of new entries at runtime that reflects the newly deployed
+applications. Apache will reload the file and update the mount
+points within 60 second interval.
+</p>
+<p>
+There is no way to delete entries by dynamic reloading, but you can disable or
+exclude mappings.
+<br/>
+<br/>
+</p>
+
+</subsection>
+
+<subsection name="Using SetHandler and Environment Variables">
+<p>
+Alternatively to the mod_jk specific directives, you can also use
+SetHandler and environment variables to control, which requests
+are being forwarded via which worker. This gives you more flexibility,
+but the results might be more difficult to understand. If you mix both
+ways of defining the forwards, in general to mod_jk directives will win.
+</p>
+<p>
+<b>SetHandler jakarta-servlet</b> forces requests to be handled by mod_jk.
+If you neither specify any workers via JkMount and the related directives,
+not via the environment variable described below,
+the first worker in the list of all worker will be chosen. You can use SetHandler
+for example in Location blocks or with Apache 2.2 also in RewriteRule.
+</p>
+<p>
+In order to control the worker using <b>SetEnvIf</b> or <b>RewriteRule</b>
+for more complex rules, you can set the environment variable <b>JK_WORKER_NAME</b>
+to the name of your chosen target worker. This enables you to decide on
+the chosen worker in a more flexible way, including dependencies on cookie values.
+This feature has been added in version 1.2.19 of mod_jk.
+</p>
+<p>
+In order to use another variable than <b>JK_WORKER_NAME</b>, you can set the name
+of this variable via the <b>JkWorkerIndicator</b> directive.
+</p>
+<p>
+You can also define exclusions from mod_jk forwards by setting the environment
+variable <b>no-jk</b>.
+</p>
+<source>
+ # Automatically map all encoded urls
+ &lt;Location *;jsessionid=&gt;
+ SetHandler jakarta-servlet
+ SetEnv JK_WORKER_NAME my_worker
+ &lt;/Location&gt;
+
+ # Map all subdirs to workers via naming rule
+ # and exclude static content.
+ &lt;Location /apps/&gt;
+ SetHandler jakarta-servlet
+ SetEnvIf REQUEST_URI ^/apps/([^/]*)/ JK_WORKER_NAME=$1
+ SetEnvIf REQUEST_URI ^/apps/([^/]*)/static no-jk
+ &lt;/Location&gt;
+</source>
+<p>
+Finally, starting with version 1.2.27 you can use the environment variable
+<b>JK_REPLY_TIMEOUT</b> to dynamically set a reply timeout.

+<li>
+<b>isapi_redirect.dll</b> - The IIS server plugin, either obtain a pre-built DLL or build it yourself (see the build section).
+</li>
+<li>
+<b>workers.properties</b> - A file that describes the host(s) and port(s) used by the workers (Tomcat processes).
+A sample workers.properties can be found under the conf directory.

+By default its value is 1, which means we use the SF_NOTIFY_AUTH_COMPLETE
+event. If you set this to 0, then we use SF_NOTIFY_PREPROC_HEADERS.
+This might be needed for IIS 5.1 when handling requests using the
+PUT HTTP method.
+</p>
+<p>This directive has been added in version 1.2.21</p>
+</attribute>
+<attribute name="uri_select" required="false"><p>
+A string value which influences, how URIs are decoded and re-encoded
+between IIS and Tomcat. You should leave this at it's default value,
+unless you have a very good reason to change it.
+</p>
+<p>
+If the value is "parsed", the forwarded URI
+will be decoded and explicit path components like ".." will already
+be resolved. This is less spec compliant and is <b>not safe</b>
+if you are using prefix forwarding rules.
+</p>
+<p>
+If the value is "unparsed", the forwarded URI
+will be the original request URI. It's spec compliant and also
+the safest option. Rewriting the URI and then forwarding the rewritten
+URI will not work.
+</p>
+<p>
+If the value is "escaped", the forwarded URI
+will be the re-encoded form of the URI used by "parsed".
+Explicit path components like ".." will already be resolved.
+This will not work in combination with URL encoded session IDs.
+</p>
+<p>
+If the value is "proxy", the forwarded URI
+will be a partially re-encoded form of the URI used by "parsed".
+Explicit path components like ".." will already be resolved.
+and problematic are re-encoded.
+</p>
+<p>The default value since version 1.2.24 is "proxy". Before it was "parsed".</p>
+</attribute>
+<attribute name="reject_unsafe" required="false"><p>
+A string value representing a boolean. If it is set to true,
+URLs containing percent signs '%' or backslashes '\'
+after decoding will be rejected.
+</p>
+<p>
+Most web apps do not use such URLs. By enabling "reject_unsafe" you
+can block several well known URL encoding attacks.
+</p>
+<p>
+A true value can be represented by the string "1" or any string starting
+with the letters "T" or "t". A false value will be assumed for "0"
+or any string starting with "F" or "f". The default value is false.
+</p>
+<p>This directive has been added in version 1.2.24</p>
+</attribute>
+<attribute name="watchdog_interval" required="false"><p>
+A DWORD value representing the watchdog thread interval in seconds.
+The workers are maintained periodically by a background thread
+running periodically every watchdog_interval seconds. Worker maintenance
+checks for idle connections, corrects load status and is able
+to detect backend health status.
+</p>
+<p>
+The maintenance only happens, if since the last maintenance at
+least <a href="workers.html"><code>worker.maintain</code></a>
+seconds have passed. So setting the watchdog_interval
+much smaller than <code>worker.maintain</code> is not useful.
+</p>
+<p>
+The default value is 0 seconds, meaning the watchdog thread
+will not be created, and the maintenance is done in combination
+with normal requests instead.
+</p>
+<p>This directive has been added in version 1.2.27</p>
+</attribute>
+<attribute name="error_page" required="false"><p>
+A string value representing the error page url redirection when
+backend returns non-200 response. This directive can be used
+to customise the error messages returned from backend server.
+</p>
+<p>The url must point to a valid server url and can contain
+format string number <code>(%d)</code> that can be used to
+separate the pages by error number. The redirect url in that
+case is formatted by replacing <code>%d</code> from
+<code>error_page</code> to returned error number.
+</p>
+<p>This directive has been added in version 1.2.27</p>
+</attribute>
+<attribute name="enable_chunked_encoding" required="false"><p>
+A string value representing a boolean. If it is set to true,
+chunked encoding is supported by the server.
+</p>
+<p>
+A true value can be represented by the string "1" or any string starting
+with the letters "T" or "t". A false value will be assumed for "0"
+or any string starting with "F" or "f". The default value is false.
+</p>
+<warn>This option is considered experimental and its support
+must be compile time enabled. Use <code>isapi_redirect.dll</code>
+with chunked support enabled.
+</warn>
+<p>This directive has been added in version 1.2.27</p>
+</attribute>
+</attributes>
+</section>
+<section name="Using a properties file for configuration">
+<p>
+The ISAPI redirector can read it's configuration from a properties file instead of the registry.
+This has the advantage that you can use multiple ISAPI redirectors with independent configurations on the same server.
+The redirector will check for the properties file during initialisation, and use it in preference to the registry if present.
+</p>
+<p>
+Create a properties file in the same directory as the ISAPI redirector called <b>isapi_redirect.properties</b> i.e. with the same name as the ISAPI redirector DLL but with a <em>.properties</em> extension. A sample isapi_redirect.properties can be found under the conf directory.
+</p>
+<p>
+The property names and values in the properties file are the same as for the registry settings described above. For example:
+</p>
+<p>
+<source>
+# Configuration file for the Jakarta ISAPI Redirector
+
+# The path to the ISAPI Redirector Extension, relative to the website
+# This must be in a virtual directory with execute privileges
+extension_uri=/jakarta/isapi_redirect.dll
+
+# Full path to the log file for the ISAPI Redirector
+log_file=c:\tomcat\logs\isapi_redirect.log
+
+# Log level (debug, info, warn, error or trace)
+log_level=info
+
+# Full path to the workers.properties file
+worker_file=c:\tomcat\conf\workers.properties
+
+# Full path to the uriworkermap.properties file
+worker_mount_file=c:\tomcat\conf\uriworkermap.properties
+</source>
+</p>
+<p>
+ Notes:
+ <ul>
+ <li>
+ Back-slashes - '\' - are not escape characters.
+ </li>
+ <li>
+ Comment lines begin with '#'.
+ </li>
+ </ul>
+</p>
+<p>Starting with version 1.2.27 two environment variables are
+dynamically added to the environment that can be used inside
+<code>.properties</code> files.
+ <ul>
+ <li>JKISAPI_PATH - Full path to the ISAPI Redirector.
+ </li>
+ <li>JKISAPI_NAME - Name of the ISAPI Redirector dll without extension
+ </li>
+ </ul>
+</p>
+<p><source>
+# Use the logs in the installation path of ISAPI Redirector
+log_file=$(ISAPI_PATH)\$(ISAPI_NAME).log
+</source></p>
+</section>
+
+<section name="Log file rotation">
+<p>
+The ISAPI redirector with version 1.2.31 can perform log rotation, with configuration and behaviour similar to the
+<a href="http://httpd.apache.org/docs/2.0/programs/rotatelogs.html">rotatelogs</a> program provided with Apache HTTP Server.
+</p>
+<p>
+To configure log rotation, configure a <b>log_file</b>, and one of the <b>log_rotationtime</b> or <b>log_filesize</b> options.
+If both are specified, the <b>log_rotationtime</b> will take precedence, and <b>log_filesize</b> will be ignored.
+<br/>For example, to configure daily rotation of the log file:
+</p>
+<source>
+# Configuration file for the Jakarta ISAPI Redirector
+...
+
+# Full path to the log file for the ISAPI Redirector
+log_file=c:\tomcat\logs\isapi_redirect.%Y-%m-%d.log
+
+# Log level (debug, info, warn, error or trace)
+log_level=info
+
+# Rotate the log file every day
+log_rotationtime=86400
+
+...
+</source>
+<p>
+Or to configure rotation of the log file when it reaches 5MB in size:
+</p>
+<source>
+# Configuration file for the Jakarta ISAPI Redirector
+...
+
+# Full path to the log file for the ISAPI Redirector
+log_file=c:\tomcat\logs\isapi_redirect.%Y-%m-%d-%H.log
+
+# Log level (debug, info, warn, error or trace)
+log_level=info
+
+# Rotate the log file at 5 MB
+log_filesize=5M
+
+...
+</source>
+<p>
+The log will be rotated whenever the configured limit is reached, but only if the log file name would change. If you configure
+ a log file name with <code>strftime(3)</code> format codes in it, then ensure it specifies the same granularity
+ as the rotation time configured, e.g. <b>%Y-%m-%d</b> if rotating daily (<b>log_rotationtime=86400</b>).
+<br/>See the <a href="http://httpd.apache.org/docs/2.0/programs/rotatelogs.html">rotatelogs</a> documentation for more examples.
+</p>
+
+</section>
+
+<section name="Using a simple rewrite rules">
+<p>
+The ISAPI redirector with version 1.2.16 can do a simple URL rewriting. Although not
+as powerful as Apache Httpd's mod_rewrite, it allows a simple exchange of request URIs
+</p>
+<p>
+The rule is in the form original-url-prefix=forward-url-prefix. For example:
+</p>
+<source>
+# Simple rewrite rules, making /jsp-examples
+# and /servlets-examples available under shorter URLs
+/jsp/=/jsp-examples/
+/servlets/=/servlets-examples/
+</source>
+<p>
+You can also use regular expressions, if you prefix the rule with a tilde <code>~</code>:
+</p>
+<source>
+# Complex rewrite rule, adding "-examples"
+# to the first path component of all requests
+~/([^/]*)=/$1-examples
+</source>
+<p>
+Note that uriworkermap.properties must use the URLs before rewriting.

+
+<body>
+
+<section name="Introduction">
+<br/>
+<p>
+Tomcat Connectors has a special type of worker, the so-called status worker.
+The status worker does not forward requests to Tomcat instances. Instead it allows
+to retrieve status and configuration information at runtime,
+and furthermore to change many configuration items dynamically. This can be done
+via a simple embedded web interface.
+</p>
+<p>
+The status worker is especially powerful, when used together with load balancing workers.
+</p>
+<p>
+This document does not explain the HTML user interface of the status worker.
+Until now it is very simple, so just go ahead and use it. This doc instead
+tries to explain the less obvious features of the status worker. We also will give a
+complete coverage of the various request parameters and their meaning, so that you can
+include the status worker in your automation scripts.
+</p>
+<p>
+The documentation of the status worker starts with <b>jk 1.2.20</b>
+</p>
+</section>
+
+<section name="Usage Patterns">
+<br/>
+<subsection name="Actions">
+<br/>
+<p>
+The status worker knows about six actions.
+<ul>
+<li>
+<b>list</b>: lists the configurations and runtime information of all configured workers.
+The output will be grouped by global information first (version data), then load balancer
+information, after that AJP worker information and finally the legend. For load balancers,
+there will be a summary part, and after that details for each member worker. For all workers,
+we also include the URL mappings (forward definitions).
+</li>
+<li>
+<b>show</b>: the same as list, but only shows data for one chosen worker
+</li>
+<li>
+<b>edit</b>: produces a form to edit configuration data for a chosen worker. There is a
+special subtype of "edit", that makes it easy to change one attribute for all members of
+a load balancer, e.g. their activation state.
+</li>
+<li>
+<b>update</b>: commit changes made in an edit form. <b>Caution</b>: the changes will not be
+persisted to the configuration files. As soon as your restart your web server, all changes
+made through the status worker will be lost! On the other hand, the changes done by the status
+worker will be applied during runtime without a restart of the web server.
+</li>
+<li>
+<b>reset</b>: reset all runtime statistics for a worker.
+</li>
+<li>
+<b>recover</b>: Mark a member of a load balancer, that is in error state, for immediate recovery.
+</li>
+<li>
+<b>version</b>: only show version information of the web server and the JK software
+</li>
+<li>
+<b>dump</b>: list the original workers configuration. <b>Caution</b>: the dump will only contain
+the configuration that was used during startup. Any changes applied later by the dynamic management
+interface of the status worker itself will not be contained in this dump.
+The dump action has been added in version 1.2.27.
+</li>
+</ul>
+</p>
+</subsection>
+
+<subsection name="Output Format">
+<br/>
+<p>
+For most actions you can choose between 4 output formats.
+<ul>
+<li>
+<b>HTML</b>: Used interactively with a browser
+</li>
+<li>
+<b>XML</b>: Mostly useful for automation, when your scripting environment is XML friendly.
+This format has rich structure information, but does not work line based, so you would really
+like to use it together with XML tools.
+</li>
+<li>
+<b>Properties</b>: This format is a line based format, that conforms to the rules of Java
+property files. Most structure information is contained in the hierarchical key. For information,
+that is of configuration nature, the format should produce lines very similar to the ones you can
+use in workers.properties. It will not produce a complete configuration file!
+</li>
+<li>
+<b>Text</b>: A simple textual output format.
+</li>
+</ul>
+The "edit" action does only make sense for the HTML output type.
+</p>
+</subsection>
+
+<subsection name="User Interface Features">
+<br/>
+<p>
+In the HTML view, there is an <b>automatic refresh</b> feature, implemented via the meta refresh
+option of HTML. Once you start the automatic refresh, the UI will will respect it for all actions
+except edit, update and maintain. Even if you navigate through one of those, the automatic refresh
+will start again as soon as you come back to one of the other actions.
+</p>
+<p>
+Many parts of the HTML page can be minimised, if they are not interesting for you. There are a couple
+of "Hide" links, which will collapse parts of the information. The feature exists for the following
+blocks of information:
+<ul>
+<li>
+<b>Legend</b>: Do not show the legend for the information presented in "list" and "show" actions
+</li>
+<li>
+<b>URI mappings</b>: Do not show the URI mapping for the workers
+</li>
+<li>
+<b>Load Balancing Workers</b>: Do not show workers of type "lb"
+</li>
+<li>
+<b>AJP Workers</b>: Do not show workers of type ajp
+</li>
+<li>
+<b>Balancer Members</b>: Do not show detailed information concerning each member of load balancers
+</li>
+<li>
+<b>Load Balancer Configuration</b>: Do not show configuration data for load balancers
+</li>
+<li>
+<b>Load Balancer Summary</b>: Do not show status summary for load balancers
+</li>
+<li>
+<b>AJP Configuration</b>: Do not show configuration data for ajp workers load balancer members
+</li>
+</ul>
+The last three minimisation features have been added in version 1.2.27.
+</p>
+</subsection>
+
+<subsection name="Special Considerations concerning URL Maps and Virtual Hosts">
+<br/>
+<p>
+<b>Note: </b>The following restriction has been removed starting with version 1.2.26.
+</p>
+<p>
+The Apache module mod_jk makes use of the internal Apache httpd infrastructure concerning
+virtual hosts. The downside of this is, that the status worker can only show URL maps, for
+the virtual host it is defined in. It is not able to reach the configuration objects
+for other virtual hosts. Of course you can define a status worker in any virtual host you
+are using. All information presented apart from the URL maps will be the same, independent
+of the virtual host the status worker has been called in.
+</p>
+</subsection>
+
+<subsection name="Logging">
+<br/>
+<p>
+The status worker will log changes made to the configuration with log level "info" to the usual
+JK log file. Invalid requests will be logged with log level "warn". If you want to report some
+broken behaviour, log file content of level "debug" or even "trace" will be useful.
+</p>
+</subsection>
+
+</section>
+
+<section name="Configuration">
+<br/>
+<subsection name="Basic Configuration">
+<br/>
+<p>
+The basic configuration of a status worker is very similar to that of a usual ajp worker.
+You need to specify a name for the worker, and the URLs you want to map to it. The first
+part of the configuration happens in the workers.properties file. We define a worker named
+mystatus of type status:
+<source>
+worker.list=mystatus
+worker.mystatus.type=status
+</source>
+Then we define a URL, which should be mapped to this worker, i.e. the URL we use
+to reach the functionality of the status worker. You can use any method mod_jk supports
+for the web server of your choice. Possibilities are maps inside uriworkermap.properties,
+an additional mount attribute in workers.properties, or in Apache JkMount. Here's an
+example for a uriworkermap.properties line:
+<source>
+/private/admin/mystatus=mystatus
+</source>
+The URI pattern is case sensitive.
+</p>
+<p>
+As you will learn in the following sections, the status worker is very powerful. You should
+use the usual authentication and authorisation methods of your web server to secure this URL.
+</p>
+<p>
+You can also define multiple instances of the status worker, by using different names and URL mappings.
+For instance you might want to configure them individually
+and then allow special groups of people to use them
+</p>
+</subsection>
+
+<subsection name="Output Customisation">
+<br/>
+<p>
+There are a couple of attributes for the workers.properties entries, which allow to customise
+various aspects of the output of the status worker.
+</p>
+<p>
+The attribute <b>css</b> can be set to the URL of a stylesheet:
+<source>
+worker.mystatus.css=/private/admin/static/mystatus.css
+</source>
+When writing HTML output, the status worker then includes the line
+<source>
+&lt;link rel="stylesheet" type="text/css" href="/private/admin/static/mystatus.css" /&gt;
+</source>
+There is no sample stylesheet included with the mod_jk release, and by default the attribute css
+is empty, so no stylesheet reference will be included in the pages. The HTML code
+of the status worker output pages does not include any class attributes. If you like to contribute a
+stylesheet or improvements to the HTML layout, please contact us on the tomcat developers list.
+</p>
+<p>
+The properties output format can be customised via the attribute <b>prefix</b>. The names of all
+properties the status worker does output, will begin with this prefix. The default is "worker".
+</p>
+<p>
+Several attributes influence the format when writing XML output.
+The attribute <b>ns</b> allows to set a namespace prefix, that will be used for every status worker+element.
+The default is "jk:". Setting it to "-" disables the namespace prefix.
+</p>
+<p>
+With the attribute xmlns you can map the prefix to a namespace URL. The default value
+is xmlns:jk="http://tomcat.apache.org". Setting it to "-" disables the output of the URL.
+</p>
+<p>
+Finally you can specify an XML document type via the attribute doctype. The specified string will
+be inserted at the beginning of the document, directly after the xml header. The default is empty.
+</p>
+</subsection>
+
+<subsection name="Securing Access">
+<br/>
+<p>
+We urge you to use the builtin access control features of your web server to control
+access to the status worker URLs you have chosen. Nevertheless two configuration
+attributes of status workers are helpful. The attribute "read_only" disables all features of
+the status worker, that can be used to change configurations or runtime status of the other workers.
+A read_only status worker will not allow access to the edit, update, reset or recover actions.
+The default value is "False", ie. read/write. To enable read_only you need to set it to "True".
+</p>
+<p>
+You could configure two status workers, one has read_only and will be made available to a larger
+admin group, the other one will be used fully featured, but only by fewer people:
+<source>
+worker.list=jk-watch

+</source>
+Starting with version 1.2.21, a read/write status worker can also be switched temporarily
+into read-only mode by the user via a link in the HTML GUI. The user can always switch it
+back to read/write. Only a status worker configured as read-only via the "read_only" attribute
+is completely safe from applying any changes.
+</p>
+<p>
+The other attribute you can use is <b>user</b>. By default this list is empty, which means
+no limit on the users. You can set "user" to a comma separated list of user names. If your
+web server is configured such that it sends the user names with the request, the status worker
+will check, if the name attached with the request is contained in it's "user" list.
+</p>
+<p>
+The user list can be split over multiple occurrences of the "user" attribute.
+</p>
+<p>
+By default, the user names are matched case sensitively. Starting with version 1.2.21 you can set
+the attribute <b>user_case_insensitive</b> to "True". Then the comparison will be made case insensitive.

+<subsection name="Service Availability Rating">
+<br/>
+<p>
+For load balancing workers the status worker shows some interesting overview information.
+It categorises the members of the load balancer into the classes "good", "bad" and degraded".
+This feature can be combined with external escalation procedures. Depending on your global
+system design and your operating practises your preferred categorisation might vary.
+</p>
+<p>
+The categorisation is based on the activation state of the workers (active, disabled or stopped),
+which is a pure configuration state, and the runtime state
+(OK or ERR with possible substates idle, busy, recovering, probing, and forced recovery)
+which only depends on the runtime situation.
+</p>
+<p>
+The runtime substates have the following meaning:
+<ul>
+<li>
+<b>OK (idle)</b>: This worker didn't receive any request since the last balancer
+maintenance. By default balancer maintenance runs every 60 seconds. The
+worker should be OK, but since we didn't have to use it for some time, we
+can't be sure. This state has been called N/A before version 1.2.24.
+</li>
+<li>
+<b>OK (busy)</b>: All connections for this worker are in use for requests.
+</li>
+<li>
+<b>ERROR (recovering)</b>: The worker was in error state for some time and is now
+marked for recovery. The next request suitable for this worker will use it.
+</li>
+<li>
+<b>ERROR (probing)</b>: After setting the worker to recovering, we received a request
+suitable for this worker. This request is now using the worker.
+</li>
+<li>
+<b>ERROR (forced recovery)</b>: The worker is in error, but we don't have an alternative
+worker, so we keep using it.
+</li>
+</ul>
+</p>
+<p>
+By default the status worker groups into "good" all members, that have activation "active" and
+runtime state not equal to "error" with empty substate.
+The "bad" group consists of the members, that have either activation
+"stopped", or are in runtime state "error" with empty substate.
+</p>
+<p>
+Workers that fit neither of the two groups, are considered to be "degraded".
+</p>
+<p>
+You can define other rules for the grouping into good, bad and degraded.
+The two attributes "good" and "bad" can be populated by a comma-separated list ob single characters or
+dot-separated pairs. Each character stands for the first character of one of the possible states "active",
+"disabled", "stopped", "ok", "idle", "busy", "recovering" and "error". The additional states "probing"
+and "forced recovery" are always rated equivalent to "recovering".
+Comma-separated entries will be combined
+with logical "or", if you combine a configuration and a runtime state with a dot. the are combined with logical
+"and". So the default value for "good" is "a.o,a.i,a.b,a.r", for "bad" it is "e,s".
+</p>
+<p>
+The status worker first tries to match against the "bad" definitions, if this doesn't succeed
+it tries to match against "good", and finally it chooses "degraded", if no "bad" or "good" match
+can be found.

+
+<section name="Request Parameters">
+<br/>
+<p>
+This section should help you building automation scripts based on the jk status
+management interface. This interface is stable in the sense, that we only expect
+to add further parameters in the future. Existing parameters from previous versions
+will keep their original semantics. We also expect the output formats XML, Properties
+and Text to be kept stable. So please use those, if you want to parse status worker
+output in your automation scripts.
+</p>
+<subsection name="Actions">
+<br/>
+<p>
+The action is determined by the parameter <b>cmd</b>. It can have the values "list", "show",
+"edit", "update", "reset", "recover", "version" and "dump". If you omit the <b>cmd</b> parameter,
+the default "list" will be used.
+All actions except for "list", "refresh", "version" and "dump" need additional parameters.
+</p>
+<p>
+The action "dump" has been added in version 1.2.27.
+</p>
+</subsection>
+<subsection name="Output Format">
+<br/>
+<p>
+The format is determined by the parameter <b>mime</b>. It can have the values "html", "xml",
+"txt" and "prop". If you omit the <b>mime</b> parameter, the default "html"
+will be used. The action "edit" (the edit form) does only make sense for "mime=html".
+</p>
+</subsection>
+<subsection name="Worker Selection">
+<br/>
+<p>
+Actions that operate on a single worker need one or two additional parameters to select
+this worker. The parameter <b>w</b> contains the name of the worker from the worker list.
+If an action operates on a member (sub worker) of a load balancer, the parameter <b>w</b>
+contains the name of the load balancer worker, and the additional parameter <b>sw</b> contains the
+name of the sub worker.
+</p>
+</subsection>
+<subsection name="Automatic Refresh">
+<br/>
+<p>
+During automatic refresh, the parameter <b>re</b> contain the refresh interval in seconds.
+If you omit this parameter, automatic refresh will be off.
+</p>
+</subsection>
+<subsection name="Hide Options">
+<br/>
+<p>
+The parameter <b>opt</b> contains a bit mask of activated options. The default is 0, so
+by default no options are activated. The following options exist:
+<ul>
+<li>
+<b>0x0001</b>: hide members of lb workers
+</li>
+<li>
+<b>0x0002</b>: hide URL maps
+</li>
+<li>
+<b>0x0004</b>: hide the legend
+</li>
+<li>
+<b>0x0008</b>: hide load balancer workers
+</li>
+<li>
+<b>0x0010</b>: hide ajp workers
+</li>
+<li>
+<b>0x0020</b>: only allow read_only actions for a read/write status worker.
+</li>
+<li>
+<b>0x0040</b>: hide load balancer configuration
+</li>
+<li>
+<b>0x0080</b>: hide load balancer status summary
+</li>
+<li>
+<b>0x0100</b>: hide configuration for ajp and load balancer member workers
+</li>
+</ul>
+Values 0x0040-0x0100 have been added in version 1.2.27.
+</p>
+</subsection>
+<subsection name="Data Parameters for the standard Update Action">
+<br/>
+<p>
+You can use the edit action with a final click to the update button, to change settings of workers.
+But you can also make direct calls to the update action. The following request parameters
+contain the configuration information, you want to change. First the list for load balancer workers:
+<ul>
+<li>
+<b>vlr</b>: retries (number)
+</li>
+<li>
+<b>vlt</b>: recover_time (seconds)
+</li>
+<li>
+<b>vlee</b>: error_escalation_time (seconds)
+</li>
+<li>
+<b>vlx</b>: max_reply_timeouts (number)
+</li>
+<li>
+<b>vls</b>: sticky_session (0/f/n/off=off, 1/t/y/on=on; case insensitive)
+</li>
+<li>
+<b>vlf</b>: sticky_session_force (0/f/n/off=off, 1/t/y/on=on; case insensitive)
+</li>
+<li>
+<b>vlm</b>: method (0/r="Requests", 1/t="Traffic", 2/b="Busyness", 3/s="Sessions"; case insensitive, only first character is used)
+</li>
+<li>
+<b>vll</b>: lock (0/o="Optimistic", 1/p="Pessimistic"; case insensitive, only first character is used)
+</li>
+</ul>
+And now the list of parameters you can use to change settings for load balancer members:
+<ul>
+<li>
+<b>vwa</b>: activation flag (0/a="active", 1/d="disabled", 2/s="stopped"; case insensitive, only first character is used)
+</li>
+<li>
+<b>vwf</b>: load balancing factor (integer weight)
+</li>
+<li>
+<b>vwn</b>: route for use with sticky sessions (string)
+</li>
+<li>
+<b>vwr</b>: redirect to define simple failover rules (string)
+</li>
+<li>
+<b>vwc</b>: domain to tell JK about your replication design (string)
+</li>
+<li>
+<b>vwd</b>: distance to express preferences (integer)
+</li>
+</ul>
+Finally the list of parameters you can use to change settings for ajp workers and ajp load balancer members:
+<ul>
+<li>
+<b>vahst</b>: host (string)
+</li>
+<li>
+<b>vaprt</b>: port (number)
+</li>
+<li>
+<b>vacpt</b>: connection_pool_timeout (number)
+</li>
+<li>
+<b>vact</b>: connect_timeout (number)
+</li>
+<li>
+<b>vapt</b>: prepost_timeout (number)
+</li>
+<li>
+<b>vart</b>: reply_timeout (number)
+</li>
+<li>
+<b>var</b>: retries (number)
+</li>
+<li>
+<b>varo</b>: recovery_options (number)
+</li>
+<li>
+<b>vamps</b>: max_packet_size (number)
+</li>
+</ul>
+Note that changing the host name or port will only take effect for new connections.
+Already established connections to the old address will still be used.
+Nevertheless this feature is interesting, because you can provision load balancer
+members with port "0", which will automatically be stopped during startup. Later
+when you know the final names and ports, you can set them and they will be
+automatically activated.
+</p>
+<p>
+The leading character "v" has been added to the parameters in version 1.2.27.
+Changing settings for ajp workers has also been introduced in version 1.2.27.
+</p>
+<p>
+For the details of all parameters, we refer to the <a href="workers.html">workers.properties Reference</a>.
+</p>
+</subsection>
+<subsection name="Aspect Editing for Load Balancer Members">
+<br/>
+<p>
+You can use the edit action to edit all settings for a load balancer or for a
+member of a load balancer respectively on one page. If you want to edit one
+configuration aspect for all members of a load balancer simultaneously, this
+will be triggered by the parameter <b>att</b>. The value of the parameter indicates,
+which aspect you want to edit. The list is the same as in the previous section,
+except for "vahst" and "vaprt":
+"vwa", "vwf", "vwn", "vwr", "vwc", "vwd", "vacpt", "vact", "vapt", "vart", "var",
+"varo" and "vamps". But here you
+need to put the name into the parameter <b>att</b>, instead of using it as a request
+parameter name.
+</p>
+<p>
+The values of the common aspect for all the load balancer members will be given
+in parameters named "val0", "val1", ....

+<section name="Introduction">
+<br/>
+<p>
+The forwarding of requests from the web server to tomcat gets configured by defining mapping rules.
+Such a rule maps requests to workers. The request part of the map is described by a URI pattern,
+the worker by it's worker name.
+</p>
+<p>
+The so-called <b>uriworkermap</b> file is a mechanism of defining rules,
+which works for all web servers. There exist also other web server specific configuration
+options for defining rules, which will be mostly discussed on the reference pages for
+configuring tomcat connectors for the individual web servers.
+</p>
+<p>
+The name of the file is usually uriworkermap.properties,
+although this is configurable in the web server.
+Please consult the web server specific documentation pages on
+how to enable the uriworkermap file.
+</p>
+<p>
+The main features supported by the uriworkermap file are
+<ul>
+<li>
+Support for comments in the rule file.
+</li>
+<li>
+Exact and wildchar matches, shortcuts to map a directory and all including content.
+</li>
+<li>
+Exclusion rules, disabling of rules and rule priorities.
+</li>
+<li>
+Rule extensions, modifying worker behaviour per rule.
+</li>
+<li>
+Virtual host integration: uri mapping rules can be expressed per virtual host.
+The details are web server specific though.
+</li>
+<li>
+Dynamic reloading: The file gets checked periodically for changes.
+New versions are automatically reloaded without web server restarts.
+</li>
+<li>
+Integration with the status worker.
+</li>
+</ul>
+The following sections describe these aspects in more detail.
+</p>
+</section>
+
+<section name="Syntax">
+<br/>
+<subsection name="Line format">
+<br/>
+<p>
+The file has a line based format. There are no continuation characters,
+so each rule needs to be defined on a single line. Each rule is a pair consisting
+of a URI pattern and a worker name, combined by an equals sign '=':
+<source>
+ /myapp=myworker
+</source>
+The URI pattern is case sensitive.
+</p>
+</subsection>
+<subsection name="Comments, white space">
+<br/>
+<p>
+All text after and including the character '#' gets ignored and can be used for comments.
+Leading and trailing white space gets trimmed around the URI pattern and also around the worker name.
+The following definitions are all equivalent:
+<source>
+ # This is a white space example
+ /myapp=myworker
+ /myapp=myworker
+ /myapp = myworker
+</source>
+</p>
+</subsection>
+
+<subsection name="URI patterns">
+<br/>
+<p>
+Inside the URI pattern three special characters can be used, '*', '?' and '|'.
+The character '*' is a wildchar that matches any number of arbitrary characters
+in the URI, '?' matches exactly one character.
+Each URI pattern has to start with the character '/', or with '*' or with '?',
+optionally prefixed by any combination of the modifiers '!' and '-' (see next section).
+<source>
+ # Mapping the URI /myapp1 and everything under /myapp1/:
+ /myapp1=myworker-a
+ /myapp1/*=myworker-a
+ # Mapping all URI which end with a common suffix:
+ *.jsp=myworker
+ *.do=myworker
+</source>
+Since the first case of mapping a certain location and everything inside
+it is very common, the character '|' gives a handy shortcut:
+<source>
+ # Mapping the URI /myapp1 and everything under /myapp1/:
+ /myapp1|/*=myworker-a
+</source>
+The pattern 'X|Y' is exactly equivalent to the two maps 'X' and 'XY'.
+</p>
+</subsection>
+</section>
+
+<section name="Exclusion, Disabling and Priorities">
+<br/>
+
+<subsection name="Exclusions and rule disabling">
+<br/>
+<p>
+Exclusion rules allows to define exclusions from URI rules, which would forward
+requests to tomcat. If the exclusion rule matches, the request will not be forwarded.
+This is usually used to serve static content by the web server.
+A rule is an exclusion rule, if it is suffixed with '!':
+<source>
+ # Mapping the URI /myapp and everything under /myapp/:
+ /myapp|/*=myworker
+ # Exclude the subdirectory static:
+ !/myapp/static|/*=myworker
+ # Exclude some suffixes:
+ !*.html=myworker
+</source>
+An exclusion rule overrides a normal mapping rule only, if the worker names in the
+normal rule and in the exclusion rule are the same. Starting with version 1.2.26 of JK
+you can apply an exclusion rule to any worker, by using the star character '*' as
+the worker name in the exclusion rule.
+More complex patterns in exclusion worker names are not allowed.
+<source>
+ # Mapping the webapps /myapp1 and /myapp2:
+ /myapp1|/*=myworker1
+ /myapp2|/*=myworker2
+ # Exclude the all subdirectories static for all workers:
+ !/*/static|/*=*
+ # Exclude some suffixes for all workers:
+ !*.html=*
+</source>
+</p>
+<p>
+Rule disabling comes into play, if your web server merges rules from various sources,
+and you want to disable any rule defined previously. Since the uriworkermap file gets
+reloaded dynamically, you can use this to temporarily disable request forwarding:
+A rule gets disabled, if it is suffixed with '-':
+<source>
+ # We are not in maintenance.
+ # The maintenance rule got defined somewhere else.
+ -/*=maintenance
+</source>
+Exclusion rules can get disabled as well, then the rule starts with '-!'.
+</p>
+</subsection>
+
+<subsection name="Mapping priorities">
+<br/>
+<p>
+The most restrictive URI pattern is applied first. More precisely the URI patterns are
+sorted by the number of '/' characters in the pattern (highest number first), and
+rules with equal numbers are sorted by their string length (longest first).
+</p>
+<p>
+If both distinctions still do not suffice, then the defining source of the rule is considered.
+Rules defined in uriworkermap.properties come first, before rules defined by JkMount (Apache)
+and inside workers.properties using the mount attribute.
+</p>
+<p>
+All disabled rules are ignored. Exclusion rules are applied after all normal rules
+have been applied.
+</p>
+<p>
+There is no defined behaviour, for the following configuration conflict:
+using literally the same URI pattern in the same defining source but with
+different worker targets.
+</p>
+</subsection>
+</section>
+
+<section name="Rule extensions">
+<br/>
+<p>
+Rule extensions were added in version 1.2.27 and are not available in earlier versions.
+</p>
+<subsection name="Syntax">
+<br/>
+<p>
+Rule extensions are additional attributes, that can be attached to any rule.
+They are added at the end of the rule, each extension separated by a semicolon:
+<source>
+ # This is an extension example,
+ # setting a reply_timeout of 1 minute
+ # only for this mapping.
+ /myapp=myworker;reply_timeout=60000
+ #
+ # This is an example using multiple extensions
+ /myapp=myloadbalancer;reply_timeout=60000;stopped=member1
+</source>
+Attributes set via rule extensions always overwrite conflicting
+configurations in the worker definition file.
+</p>
+</subsection>
+<subsection name="Extension reply_timeout">
+<br/>
+<p>
+The extension <code>reply_timeout</code> sets a reply timeout for a single mapping rule.
+<source>
+ # Setting a reply_timeout of 1 minute
+ # only for this mapping.
+ /myapp=myworker;reply_timeout=60000
+</source>
+It overrides any <code>reply_timeout</code> defined for the worker. The extension allows
+to set a reasonable default reply timeout to the worker, and a more relaxed
+reply timeout to URLs, which are known to start time intensive tasks.
+For a general description of reply timeouts see the
+<a href="../generic_howto/timeouts.html#Reply Timeout">timeouts</a> documentation.
+</p>
+</subsection>
+<subsection name="Extensions active/disabled/stopped">
+<br/>
+<p>
+The extensions <code>active</code>, <code>disabled</code>, and <code>stopped</code>
+can be used in a load balancer mapping rule to set selected members
+of the load balancer into a special activation state.
+<source>
+ # Stop forwarding only for member1 of loadbalancer
+ /myapp=myloadbalancer;stopped=member1
+</source>
+Multiple members must be separated by commas or white space:
+<source>
+ # Stop forwarding for member01 and member02 of loadbalancer
+ # Disable forwarding for member21 and member22 of loadbalancer
+ /myapp=myloadbalancer;stopped=member01,member02;disabled=member21,member22
+</source>
+For the precise meaning of the activation states see the description of
+<a href="../reference/workers.html#Advanced Worker Directives">activation</a>.
+</p>
+</subsection>
+<subsection name="Extension fail_on_status">
+<br/>
+<p>
+The extension <code>fail_on_status</code> can be used in any rule:
+<source>
+ # Send 503 instead of 404 and 500,
+ # and if we get a 503 also set the worker to error
+ /myapp=myworker;fail_on_status=-404,-500,503
+</source>
+Multiple status codes must be separated by commas.
+For the precise meaning of the attribute see the description of
+<a href="../reference/workers.html#Advanced Worker Directives">fail_on_status</a>.
+</p>
+</subsection>
+<subsection name="Extension use_server_errors">
+<br/>
+<p>
+The extension <code>use_server_errors</code> allows to let the web server
+send an error page, instead of the backend (e.g. Tomcat) error page.
+This is useful, if one wants to send customized error pages, but those are
+not part of all web applications. They can then be put onto the web server.
+</p>
+<p>
+The value of <code>use_server_errors</code> is a positive number.
+Any request send to the backend, that returns with an http status
+code bigger or equal to <code>use_server_errors</code>, will
+be answered to the client with the error page of the web server
+for this status code.
+<source>
+ # Use web server error page for all errors
+ /myapp=myworker;use_server_errors=400
+ # Use web server error page only for technical errors
+ /myotherapp=myworker;use_server_errors=500
+</source>
+</p>
+</subsection>
+</section>
+
+<section name="Virtual host integration">
+<br/>
+
+<subsection name="IIS">
+<br/>
+<p>
+When using IIS you can restrict individual rules to special virtual hosts
+by prefixing the URI pattern with the virtual host information.
+The rules is that the url must be prefixed with the host name.
+<source>
+ # Use www.foo.org as virtual host
+ /www.foo.org/myapp/*=myworker
+ # Use www.bar.org as virtual host
+ /www.bar.org/myapp/*=myworker
+ # Normal mapping
+ /mysecondapp/*=myworker
+</source>
+</p>
+<p>
+Note that /mysecondapp/* will be mapped to all virtual hosts present.
+In case one needs to prevent the mappings to some particular virtual host then
+the exclusion rule must be used
+<source>
+ # Make sure the myapp is accessible by all virtual hosts
+ /myapp/*=myworker
+ # Disable mapping myapp for www.foo.org virtual host
+ !/www.foo.org/myapp/*=myworker
+</source>
+</p>
+</subsection>
+
+<subsection name="Apache httpd">
+<br/>
+<p>
+For Apache you can define individual uriworkermap files per virtual host.
+The directive JkMountFile can be used in the main server and in each virtual host.
+If a virtual host does not use JkMountfile, but JkMountCopy is set to 'On',
+then it inherits the JkMountFile from the main server. If you want all vhost to inherit
+mounts from the main server, you can set JkMountCopy to 'All' in the main server.
+</p>
+</subsection>
+</section>
+
+<section name="Dynamic reloading">
+<br/>
+<p>
+When a request is being processed, tomcat connectors check the file modification time
+of the uriworkermap file. To keep the performance penalty low, this happens only,
+if the last check happened at least n seconds ago.
+</p>
+<p>
+For Apache you can configure the interval "n" using the directive JkMountFileReload,
+for IIS you would use the attribute worker_mount_reload.
+The default value is 60 seconds. A value of "0" turns off the reloading.
+</p>
+<p>
+If the file changed, it gets reloaded completely. If there exist rules coming
+from other sources than the uriworkermap file (e.g. the workers.properties mount
+attribute or JkMount with Apache httpd), the new uriworkermap file gets dynamically
+merged with these ones exactly like when you do a web server restart.
+</p>
+<p>
+Until version 1.2.19 reloading behaved slightly differently: it continuously added
+the full contents of the uriworkermap file to the rule mapping. The merging rules
+were, that duplicated got eliminated and old rules could be disabled, by defining the
+rule as disabled in the new file. Rules never got deleted.
+</p>
+</section>
+
+<section name="Status worker integration">
+<br/>
+<p>
+The configuration view of the status worker also shows the various mapping rules.
+After each worker's configuration, the rules are listed, that forward to this worker.
+The list contains four columns:
+<ul>
+<li>
+the name of the virtual server
+</li>
+<li>

+<br/>
+<p>
+A <b>Tomcat worker</b> is a Tomcat instance that is waiting to execute servlets or any other content
+on behalf of some web server. For example, we can have a web server such as
+Apache forwarding servlet requests to a Tomcat process (the worker) running behind it.
+</p>
+<p>
+The scenario described above is a very simple one;
+in fact one can configure multiple Tomcat workers to serve servlets on
+behalf of a certain web server.
+The reasons for such configuration can be:
+</p>
+<ul>
+<li>
+We want different contexts to be served by different Tomcat workers to provide a
+development environment where all the developers share the same web server but
+own a Tomcat worker of their own.
+</li>
+<li>
+We want different virtual hosts served by different Tomcat processes to provide a
+clear separation between sites belonging to different companies.
+</li>
+<li>
+We want to provide load balancing, meaning run multiple Tomcat workers each on a
+machine of its own and distribute the requests between them.
+</li>
+</ul>
+
+<p>
+There are probably more reasons for having multiple workers but I guess that this list is enough...
+</p>
+<p>
+Tomcat workers are defined in a properties file dubbed <b>workers.properties</b> and this tutorial
+explains how to work with it.
+</p>
+</section>
+
+<section name="Configuration File Basics">
+<br/>
+<p>Defining workers to the Tomcat web server plugin can be done using a properties file
+(a sample file named workers.properties is available in the conf/ directory).
+</p>
+
+<subsection name="Format, Comments, Whitespace">
+<br/>
+<p>
+The lines in the file define properties. The general format is
+</p>
+<p><strong>&lt;name&gt;=&lt;value&gt;</strong></p>
+<p>
+</p>
+Dots are used as part of the name to represent a configuration hierarchy.
+<p>
+Invalid directives will be logged during web server startup and prevent the web server
+from working properly. Some directives have been deprecated. Although they will
+still work, you should replace them by their
+<a href="#Deprecated Worker Directives">successors</a>.
+</p>
+<p>
+Some directives are allowed multiple times. This will be explicitly
+noted in the tables below.
+</p>
+<p>
+Whitespace at the beginning and the end of a property name or value gets ignored.
+Comments can be placed in any line and start with a hash sign '#'.
+Any line contents behind the hash sign get ignored.
+</p>
+</subsection>
+
+<subsection name="Global Properties">
+<br/>
+<p>
+These directives have global scope.
+</p>
+<directives>
+<directive name="worker.list" default="ajp13" required="true">
+A comma separated list of workers names that the JK will use. When starting up,
+the web server plugin will instantiate the workers whose name appears in the
+worker.list property, these are also the workers to whom you can map requests.
+<p>
+This directive can be used multiple times.
+</p>
+</directive>
+<directive name="worker.maintain" default="60" required="false">
+Worker connection pool maintain interval in seconds. If set to the positive
+value JK will scan all connections for all workers specified in worker.list
+directive and check if connections needs to be recycled.
+<p>
+Furthermore any load balancer does a global maintenance every worker.maintain
+seconds. During global maintenance load counters are decayed and workers
+in error are checked for recover_time.
+</p>
+<p>
+This feature has been added in <b>jk 1.2.13</b>.
+</p>
+</directive>
+</directives>
+</subsection>
+
+<subsection name="Worker Properties">
+<br/>
+<p>
+Each worker configuration directive consists of three words separated by a dot:
+</p>
+<p><strong>worker.&lt;worker name&gt;.&lt;directive&gt;=&lt;value&gt;</strong></p>
+<p>
+The first word is always <b>worker</b>.
+The second word is the worker name you can choose. In the case of load-balancing,
+the worker name has an additional meaning. Please consult the
+<a href="../generic_howto/loadbalancers.html">Load Balancer HowTo</a>.
+</p>
+<warn>
+The name of the worker can contain only the alphanumeric characters
+<b>[a-z][A-Z][0-9][_\-]</b> and is case sensitive.
+</warn>
+</subsection>
+
+<subsection name="Variables, Environment Variables">
+<br/>
+<p>
+You can define and use variables in the workers.properties file.
+To define a variable you use the syntax:
+</p>
+<p><strong>&lt;variable_name&gt;=&lt;value&gt;</strong></p>
+<p>
+Dots are allowed in the variable name, but you have to be careful
+not to use variable names, that clash with standard directives.
+Therefore variable names should never start with "worker.".
+</p>
+<p>
+To use a variable, you can insert "$(variable_name)" at any place
+on the value side of a property line. If a variable has not been
+defined before its use, we will search the process environment for
+a variable with the same name and use their value.
+</p>
+</subsection>
+
+<subsection name="Property Inheritance">
+<br/>
+<p>Often one wants to use the same property values for various workers.
+To reduce duplication of configuration lines and to ease the maintenance of
+the file, you can inherit properties from one worker to another, or even
+from a template to real workers.
+</p>
+<p>
+The directive "reference" allows to copy configurations between workers
+in a hierarchical way. If worker castor sets <b>worker.castor.reference=worker.pollux</b>
+then it inherits all properties of <b>pollux</b>, except for the ones that
+are explicitly set for <b>castor</b>.
+</p>
+<p>
+Please note, that the value of the directive is not only the name of the referred worker,
+but the complete prefix including "worker.".
+</p>
+<p>
+To use a template worker simply define it like a real worker, but do not add it
+to the "worker.list" or as a member to any load balancer. Such a template worker
+does not have to contain mandatory directives. This approach is especially useful,
+if one has a lot of balanced workers in a load balancer
+and these workers share most of their properties. You can set all of these properties
+in a template worker, e.g. using the prefix "worker.template1", and then simply
+reference those common properties in all balanced workers.
+</p>
+<p>
+References can be used to inherit properties over multiple hops in a hierarchical way.
+</p>
+<p>
+This feature has been added in <b>jk 1.2.19</b>.

+
+<section name="List of All Worker Directives">
+<br/>
+<subsection name="Mandatory Directives">
+<br/>
+<p>Mandatory directives are the one that each worker <b>must</b> contain. Without them the worker will
+be unavailable or will misbehave. Those directives will be marked with a <strong>strong</strong> font in the following tables.
+</p>
+<directives>
+<directive name="type" default="ajp13" required="true">
+Type of the worker (can be one of ajp13, ajp14, jni, lb or status). The type of the worker
+defines the directives that can be applied to the worker.
+<p>AJP13 worker is the preferred worker type that JK uses for communication
+between web server and Tomcat. This type of worker uses sockets as communication
+channel. For detailed description of the AJP13 protocol stack browse to
+<a href="../ajp/ajpv13a.html">AJPv13 protocol specification</a>

+
+<subsection name="Connection Directives">
+<br/>
+<p>Connection directives defines the parameters needed to connect and maintain
+the connections pool of persistent connections between JK and remote Tomcat.
+</p>
+<directives>
+
+<directive name="host" default="localhost" required="false">
+Host name or IP address of the backend Tomcat instance. The remote Tomcat must
+support the ajp13 protocol stack. The host name can have a <b>port</b> number
+embedded separated by the colon (':') character.
+</directive>
+
+<directive name="port" default="8009" required="false">
+Port number of the remote Tomcat instance listening for defined protocol requests.
+The default value depends on the worker type. For AJP13 workers the default port is
+<b>8009</b>, while for AJP14 type of worker that value is <b>8011</b>.
+</directive>
+
+<directive name="socket_timeout" default="0" required="false">
+Socket timeout in seconds used for the communication channel between JK and remote host.
+If the remote host does not respond inside the timeout specified, JK will generate an error,

+<code>socket_connect_timeout</code> in milliseconds,
+so in absolute terms the default <code>socket_connect_timeout</code> is
+equal to <code>"socket_timeout</code>.

+generally 120 minutes), and thus prevent the firewall to cut inactive connections.
+To enable keepalive set this property value to <b>True</b>.
+<p>
+The problem with Firewall cutting inactive connections is that sometimes, neither webserver or Tomcat

+Connection pool size property is only used for multi threaded

+the number of threads per web server process. JK will discover
+this number for the Apache web server automatically and set the pool size to

+</p>
+<p>We strongly recommend adjusting this value for IIS and the Netscape/Sun

+<subsection name="Load Balancing Directives">
+<br/>
+<p>Load balancer is a virtual worker that does not really communicate with Tomcat workers.
+Instead it is responsible for the management of several "real" workers.
+The worker is supposed to be a load balancer if it's worker type is <b>lb</b>.
+See worker's <b>type</b> directive.
+</p>
+<p>Loadbalancer directives define the parameters needed to create the workers that are
+connecting to a remote cluster of backend Tomcat servers. Each cluster node has to
+have a worker defined.
+</p>
+<p>
+Load balancer management includes:
+</p>
+
+<ul>
+<li>
+Instantiating the workers in the web server.
+</li>
+<li>
+Using the worker's load-balancing factor, perform weighed-round-robin load balancing where
+high lbfactor means stronger machine (that is going to handle more requests)
+</li>
+<li>
+Keeping requests belonging to the same session executing on the same Tomcat worker.
+</li>
+<li>
+Identifying failed Tomcat workers, suspending requests to them and instead fall-backing on
+other workers managed by the lb worker.
+</li>
+</ul>
+
+<p>
+The overall result is that workers managed by the same lb worker are load-balanced
+(based on their lbfactor and current user session) and also fall-backed so a single
+Tomcat process death will not "kill" the entire site.
+</p>
+<warn>
+If you want to use session stickiness, you must set different jvmRoute attributes
+in the Engine element in Tomcat's server.xml. Furthermore the names of the workers
+which are managed by the balancer have to be equal to the jvmRoute of the Tomcat
+instance they connect with.
+</warn>

+<p>
+Some methods note, that they aggregate in a sliding time window. They add up
+accesses, and on each run of the global maintain method, the load counters

+without a session cookie or URL encoding as a new session. This method will neither
+know, when a session is being invalidated, nor will it correct its load numbers
+according to session timeouts or worker failover. This method should be used,

+For every load balancer worker, the status worker shows a summary

+"good", "bad" and "degraded".
+<p>
+These states are determined depending on the activation of the members
+(active, disabled, stopped) and their runtime state
+(ok, n/a, busy, recovering, probing, forced recovery, error).
+By default, members are assumed to be "good", if their activation
+is "active" and their runtime state is not "error".
+</p>
+<p>
+You can change this mapping, by assigning a list of values to the
+attribute "good". Each value gives a possible match for the members,
+and one match suffices. Each value is either a single character, or two
+characters combined with a dot ".". The single characters are the
+first characters in the words "active", "disabled", "stopped",
+"ok", "na", "busy", "recovering", "error". The additional states "probing"
+and "forced recovery" are always rated equivalent to "recovering".
+If a value consists only
+of a single character, then all members with this activation or runtime
+state will be assumed good. A combination of an activation and a runtime
+state concatenated with a dot "." does only apply to a member, that has
+exactly this activation and state.
