-</font></p>
-<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 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></td></tr><tr><td align="left" valign="center"><code>JkWorkerProperty</code></td><td align="left" valign="center"><p>
-Enables setting worker properties inside Apache configuration file.

-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

-<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>

-File containing multiple mappings from a context to a Tomcat worker.
-It is usually called uriworkermap.properties.

-For inheritance rules, see: JkMountCopy.
-<br>
-There is no default value.
-</p></td></tr><tr><td align="left" valign="center"><code>JkMountFileReload</code></td><td align="left" valign="center"><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></td></tr><tr><td align="left" valign="center"><code>JkMount</code></td><td align="left" valign="center"><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></td></tr><tr><td align="left" valign="center"><code>JkUnMount</code></td><td align="left" valign="center"><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.

-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.

-There is no default value.
-</p></td></tr><tr><td align="left" valign="center"><code>JkMountCopy</code></td><td align="left" valign="center"><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></td></tr><tr><td align="left" valign="center"><code>JkWorkerIndicator</code></td><td align="left" valign="center"><p>

-The default value is JK_WORKER_NAME.
-</p></td></tr><tr><td align="left" valign="center"><code>JkWatchdogInterval</code></td><td align="left" valign="center"><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"><b class="code">worker.maintain</b></a>
-seconds have passed. So setting the JkWatchdogInterval
-much smaller than <b class="code">worker.maintain</b> 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.

-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.

-</p></td></tr><tr><td align="left" valign="center"><code>JkLogStampFormat</code></td><td align="left" valign="center"><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()

-Turns on SSL processing and information gathering by mod_jk
-<br>
-The default value is On.

-In order to make SSL data available for mod_jk in Apache, you need to
-set <b class="code">SSLOptions +StdEnvVars</b>. For the certificate information you also need
-to add <b class="code">SSLOptions +ExportCertData</b>.
-</p>
-<p>
- Specifically, mod_jk will export the following environment variables from
- Apache httpd to Tomcat under these request attributes as per the

-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.
-
-<div class="example"><pre>
- JkOptions +ForwardURIProxy
-</pre></div>
-
-<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.
-
-<div class="example"><pre>
- JkOptions +ForwardURICompatUnparsed
-</pre></div>
-
-<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.
-
-<div class="example"><pre>
- JkOptions +ForwardURICompat
-</pre></div>
-
-<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.
-
-<div class="example"><pre>
- JkOptions +ForwardURIEscaped

-<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.
-
-<div class="example"><pre>
- JkOptions +RejectUnsafeURI
-</pre></div>
-
-<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 <b class="code">403 Forbidden</b> 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.
-
-<div class="example"><pre>
- JkOptions +ForwardDirectories
-</pre></div>
-<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.
-
-<div class="example"><pre>
- JkOptions +ForwardLocalAddress
-</pre></div>
-
-<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).
-
-<div class="example"><pre>
- JkOptions +FlushPackets
-</pre></div>
-
-<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.
-
-<div class="example"><pre>
- JkOptions +FlushHeader
-</pre></div>
-
-<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.
-
-<div class="example"><pre>
- JkOptions +DisableReuse
-</pre></div>
-
-<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).
-
-<div class="example"><pre>
- JkOptions +ForwardKeySize
-</pre></div>
-
-<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 <b class="code">SSL_CLIENT_CERT</b> 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 <b class="code">SSL_CLIENT_CERT_CHAIN</b> to Tomcat via the AJP connector.
-<br>
-This directive exists only since version 1.2.22.
-<div class="example"><pre>
- JkOptions +ForwardSSLCertChain
-</pre></div>
-
-<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.

-<b>JkMount</b> directive assign specific URLs to Tomcat.
-In general the structure of a JkMount directive is:
-</p>
-
-<div class="example"><pre>
- JkMount [URL prefix] [Worker name]
-</pre></div>
-
-<div class="example"><pre>
- # 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
-</pre></div>
-
-<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>
-<div class="example"><pre>
- # send all requests ending with /servlet to worker1
- JkMount /servlet/* worker1
- # do not send requests ending with .gif to worker1
- JkUnMount /servlet/*.gif worker1
-</pre></div>
-<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>
-<div class="example"><pre>
- # 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
-</pre></div>
-<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>
-<div class="example"><pre>
- # 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=*
-</pre></div>
-<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>
-<div class="example"><pre>
- # enter the full path to the tomcat webapps directory
- JkAutoAlias /opt/tomtact/webapps
-</pre></div>
-<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>
-
-<div class="example"><pre>
- # enter the full path to the tomcat webapps directory
- JkAutoAlias /opt/tomtact/webapps

- # 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
-</pre></div>
-<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>
-<div class="example"><pre>
- # 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
-</pre></div>
-<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>
-<div class="example"><pre>
- # Load mount points
-
- JkMountFile conf/uriworkermap.properties
-</pre></div>
-<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>
-<div class="example"><pre>
- # Sample uriworkermap.properties file
-
- /servlets-examples/*=ajp13w
- # Do not map .jpeg files
- !/servlets-examples/*.jpeg=ajp13w
- # Make jsp examples initially disabled
- -/jsp-examples/*=ajp13w
-</pre></div>
-<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.

-<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>
-<div class="example"><pre>
- # 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;
-</pre></div>
-<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.
