+<p>
+This document explains how to connect Tomcat to the popular open source web server, Apache httpd.
+There is actually three versions of Apache HTTP Server, 1.3, 2.0 and 2.2 and all can be used with mod_jk,
+the Tomcat redirector module.
+</p>
+
+<p>
+It is recommended that you also read the
+<a href="../../generic_howto/workers.html">Workers HowTo</a> document
+to learn how to setup the working entities between your web server and Tomcat Engines.
+For more detailed configuration information consult the Reference Guide for
+<a href="../../reference/worker.html">workers.properties</a>,
+<a href="../../reference/uriworkermap.html">uriworkermap</a>
+and <a href="../../reference/apache.html">Apache</a>.
+</p>
+
+<p><b>Waring: If Apache HTTP Server 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.</b> 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>
+This document was originally part of <b>Tomcat: A Minimalistic User's Guide</b> written by Gal Shachor,
+but has been split off for organisational reasons.

+<p>
+In a nutshell a web server is waiting for client HTTP requests.
+When these requests arrive the server does whatever is needed to serve the
+requests by providing the necessary content.
+</p>
+
+<p>
+Adding a servlet container may somewhat change this behaviour.
+Now the web server needs also to perform the following:
+</p>
+
+<ul>
+<li>
+Load the servlet container adaptor library and initialise it (prior to serving requests).
+</li>
+<li>
+When a request arrives, it needs to check and see if a certain request belongs to a servlet,
+if so it needs to let the adaptor take the request and handle it.
+</li>
+</ul>
+
+<p>
+The adaptor on the other hand needs to know what requests it is going to serve,
+usually based on some pattern in the request URL, and to where to direct these requests.
+</p>
+
+<p>
+Things are even more complex when the user wants to set a configuration that uses virtual hosts,
+or when they want multiple developers to work on the same web server
+but on different servlet container JVMs.
+We will cover these two cases in the advanced sections.

+<p>
+mod_jk can be obtained in two formats - binary and source.
+Depending on the platform you are running your web server on, a binary version of mod_jk may be available.
+</p>
+
+<p>
+It is recommended to use the binary version if one is available.
+If the binary is not available, follow the instructions for building mod_jk from source.
+The mod_jk source can be downloaded from a mirror
+<a href="http://tomcat.apache.org/download-connectors.cgi">
+here</a>
+</p>
+
+<p>
+The binaries for mod_jk are now available for several platforms.
+The binaries are located in subdirectories by platform.
+</p>
+
+<p>
+For some platforms, such as Windows, this is the typical way of obtaining mod_jk
+since most Windows systems do not have C compilers.
+</p>
+
+<p>
+For others, the binary distribution of mod_jk offers simpler installation.
+</p>
+
+<p>
+For example JK 1.2.x can be downloaded from a mirror
+<a href="http://tomcat.apache.org/download-connectors.cgi">
+here</a> (look for JK 1.2 Binary Releases). The "JK 1.2 Binary Releases" link contains binary version for a variety of

+mod_jk requires two entities:

+or MOD_JK.SRVPGM (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 in the source download.
+</li>
+</ul>
+</p>
+
+<p>
+Also as with other Apache HTTP Server modules, mod_jk should be first installed on the modules directory of your

+<p>
+The auto-configure works only for a single Tomcat running on the same machine where Apache HTTP Server is running.
+The simplest way to configure Apache HTTP Server to use mod_jk is to turn on the Apache HTTP Server auto-configure setting
+in Tomcat and put the following include directive at the end of your Apache httpd.conf file
+(make sure you replace $TOMCAT_HOME with the correct path for your Tomcat installation:
+</p>
+
+<div class="example"><pre>
+ #To be added at the end of your httpd.conf
+ Include $TOMCAT_HOME/conf/jk/mod_jk.conf-auto
+</pre></div>
+
+<p>
+Note: this file may also be generated as $TOMCAT_HOME/conf/auto/mod_jk.conf
+</p>
+
+<p>
+This will tell Apache HTTP Server to use directives in the <b>mod_jk.conf-auto</b> file in
+the Apache configuration. This file is created by enabling the Apache
+auto-configuration by creating your workers.properties file at
+$TOMCAT_HOME/conf/jk/workers.properties and adding the listener to the Engine
+element in the server.xml file as per the following example.
+<b>Please note that this example is specific to Tomcat 5.x, unlike other sections of this document
+ which also apply to previous Tomcat branches.</b>
+</p>
+<div class="example"><pre>
+ ...
+ &lt;Engine ...&gt;

+ &lt;Listener className="org.apache.jk.config.ApacheConfig" modJk="/path/to/mod_jk.so" /&gt;
+ ...
+ &lt;/Engine&gt;
+ ...
+</pre></div>
+
+<p>
+Then restart Tomcat and mod_jk.conf should be generated. For more information on
+this topic, please refer to the API documentation at the
+<a href="http://tomcat.apache.org/tomcat-5.5-doc/catalina/docs/api/org/apache/jk/config/ApacheConfig.html">

+<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.
+
+<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
+</pre></div>
+
+<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.
+
+<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>
+

+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 ForwarDirectories 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.

+ JkOptions +ForwardDirectories

+<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 (off 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.

+Since OS400 V4R5, System I (AS/400) has used Apache 2.0 as their primary web server,

+It's now possible to build mod_jk on System I thanks to the help of the IBM
+Rochester Labs which has provided information and patches to adapt mod_jk to i5/OS.
+</p>
+<p>
+You should have at least Apache 2.0.58 (product 5722DG1), a C Compiler and IFS.
+Apache 2.0.58 is provided with the most recent set of PTFs for the iSeries Apache
+server, which can be found at <a href="http://www.ibm.com/servers/eserver/iseries/software/http/">
+http://www.ibm.com/servers/eserver/iseries/software/http/</a>
+</p>
+<p>
+The all latest Apache 2 for i5/OS V5R3 (or V5R4) is now 2.0.58 (as of 2007/04/17).
+Be sure to have the latest PTFs loaded if you want to make use of jk 1.2.15 and higher.
+NB: The latest mod_jk known to work on i5/OS V5R3 was 1.2.19.
+</p>
+<p>
+New in i5/OS V5R4, UTF is required, also for Apache modules, as such Apache modules do not require
+translations to/from EBCDIC but works should be done to port mod_jk 1.2.23 (and higher) to V5R4.
+
+From the V5R4 Infocenter :
+
+As of i5/OS(tm) V5R4, modules must be recompiled with a UTF locale. This creates an environment where locale-dependent C runtime functions assume
+that string data is encoded in UTF-8. Any hardcoded constants can be encoded in UTF-8 by adding a #pragma convert(1208) statement in the module.
+Additionally, input data from the client will no longer be converted to EBCDIC but will be passed as-is.
+Output data sent from the module is not converted either so it must be encoded in ASCII or UTF8 as required.
+APR and HTTP APIs as of V5R4, expect data in UTF-8. Note that several APIs have additional functions that allow a CCSID to be set to
+indicate the encoding of the parameters being passed. Conversion functions between UTF-8 and EBCDIC have been added.
+Be sure to review APIs used by your module to be aware of current changes.

+To configure mod_jk on System I use the CL source provided with the mod_jk source.

+A pre-built version of the ISAPI redirector server plugin, isapi_redirect.dll, is available under
+the win32/i386 directory of tomcat-connectors distribution.
+For those using Netscape as your browser, try downloading a zip version of the file, if available.
+There can be problems using Netscape to download DLL files.
+
+You can also build a copy locally from the source present in tomcat-connectors distribution.
+
+The Tomcat redirector requires three entities:
+
+<ul>
+<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><a href="../../reference/workers.html">workers.properties</a></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.
+</li>
+<li>
+<b><a href="../../reference/uriworkermap.html">uriworkermap.properties</a></b> - A file that maps URL-Path patterns to workers.
+A sample uriworkermap.properties can be found under the conf directory as well.
+</li>
+</ul>
+</p>
+
+<p>
+The installation includes the following parts:
+
+<ul>
+<li>
+Configuring the ISAPI redirector with a default /examples context and checking that you can serve servlets with IIS.

+In this document I will assume that isapi_redirect.dll is placed in
+<b>c:\tomcat\bin\win32\i386\isapi_redirect.dll</b> and
+that the properties files which you created are in <b>c:\tomcat\conf</b>.
+</p>
+<p>
+<ol>
+<li>
+In the registry, create a new registry key named
+<b>"HKEY_LOCAL_MACHINE\SOFTWARE\Apache Software Foundation\Jakarta Isapi Redirector\1.0"</b>
+</li>
+<li>
+Add a string value with the name <b>extension_uri</b> and a value of <b>/jakarta/isapi_redirect.dll</b>
+</li>
+<li>
+Add a string value with the name <b>log_file</b> and a value pointing to where you want your
+log file to be (for example <b>c:\tomcat\logs\isapi.log</b>).
+</li>
+<li>
+Add a string value with the name <b>log_level</b> and a value for your log level
+(can be debug, info, error or emerg).
+</li>
+<li>
+Add a string value with the name <b>worker_file</b> and a value which is the full path
+to your workers.properties file (for example <b>c:\tomcat\conf\workers.properties</b>)
+</li>
+<li>
+Add a string value with the name <b>worker_mount_file</b> and a value which is the full path
+to your uriworkermap.properties file (for example <b>c:\tomcat\conf\uriworkermap.properties</b>)
+</li>
+<li>
+Using the IIS management console, add a new virtual directory to your IIS/PWS web site.
+The name of the virtual directory must be jakarta.
+Its physical path should be the directory where you placed isapi_redirect.dll
+(in our example it is c:\tomcat\bin\win32\i386).
+While creating this new virtual directory assign it with execute access.
+</li>
+<li>
+Using the IIS management console, add isapi_redirect.dll as a filter in your IIS/PWS web site.
+The name of the filter should reflect its task (I use the name tomcat),
+its executable must be our c:\tomcat\bin\win32\i386\isapi_redirect.dll.
+For PWS, you'll need to use regedit and add/edit the <b>"Filter DLLs"</b> key under
+<b>HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\W3SVC\Parameters</b>.
+This key contains a "," separated list of dlls (full paths) -
+you need to insert the full path to isapi_redirect.dll.
+</li>
+<li>
+If you're using IIS 6.0 you must also do the following:
+<br>
+Using the IIS management console, add the Jakarta Isapi Redirector to the Web
+Service Extensions.
+<ol>
+<li>Right-click on Web Service Extensions and choose Add a new Web Service
+Extension.</li>
+<li>Enter tomcat for the Extension Name.</li>
+<li>Add the isapi_redirect.dll to the required files.</li>
+<li>Check the Set extension status to Allowed.</li>
+<li>Click on OK.</li>
+</ol>
+</li>
+<li>
+Restart IIS (stop + start the IIS service), make sure that the tomcat filter is marked with a green up-pointing arrow.
+Under Win98 you may need to <b>cd WINDOWS\SYSTEM\inetsrv</b> and type PWS /stop
+( the DLL and log files are locked - even if you click the stop button,
+PWS will still keep the DLLs in memory. ). Type pws to start it again.
+</li>
+</ol>

+That's all, you should now start Tomcat and ask IIS to serve you the /examples context.
+Try <a href="http://localhost/examples/jsp/index.html">http://localhost/examples/jsp/index.html</a> for example and
+execute some of the JSP examples.
+</p>

+<p>
+The examples context is useful for verifying your installation,
+but you will also need to add your own contexts. Adding a new context requires two operations:
+</p>
+<p>
+<ol>
+<li>
+Adding the context to Tomcat (I am not going to talk about this).
+</li>
+<li>
+Adding the context to the ISAPI redirector.
+</li>
+</ol>
+</p>
+<p>
+Adding a context to the ISAPI redirector is simple, all you need to do is to edit
+your uriworkermap.properties and to add a line that looks like:
+</p>
+
+<div class="example"><pre>
+ /context/*=worker_name
+</pre></div>
+
+<p>
+Workers and their name are defined in workers.properties, by default workers.properties comes
+with a single pre-configured worker named <b>"defworker"</b> so you can use it.
+As an example, if you want to add a context named "shop", the line that you should add to
+uriworkermap.properties will be:
+</p>
+
+<div class="example"><pre>
+ /shop/*=defworker
+</pre></div>
+
+After saving uriworkermap.properties restart IIS and it will serve the new context.
+<p>
+The above should be all you need for IIS to pass through to Tomcat any request for any URI which corresponds
+to a Tomcat context (webapp).

+<p>
+If your webiste is very busy (more than 100 requests/second, or more than 100 simultaneous client connections),
+it might sometimes be desirable to have IIS serve static content (html, gif, jpeg etc.) directly,
+even if these files are part of a context served by Tomcat. Allowing IIS to serve such files directly may
+ avoid the small overhead consisting of passing the request to Tomcat via the redirector, and may free up
+ Tomcat somewhat, by using it only to process requests that only Tomcat can handle (e.g. requests to JSP pages and java servlets).
+</p>
+<p>
+For example, consider the html and gif files in the examples context : you could serve these files directly
+with IIS; there is no need to serve them from the Tomcat process.
+</p>
+<p><font color="#ff0000">However, you should be very careful when you implement the following configuration style, because by doing so you are
+in fact providing a "back-door" to IIS, and allowing it to serve files out of a Tomcat context without Tomcat's knowledge,
+thus bypassing any security
+restrictions which Tomcat itself and the Tomcat context (webapp) may place on those files.</font></p>
+<p>
+Making IIS serve static files that are part of the Tomcat contexts requires the following:
+<ol>
+<li>
+Configuring IIS to know about the Tomcat contexts
+</li>
+<li>
+Configuring the redirector to leave the static files for IIS
+</li>
+</ol>
+</p>
+
+<p>
+Adding a Tomcat context to IIS requires the addition of a new IIS virtual directory that covers the Tomcat context.
+For example adding a /example IIS virtual directory that covers the c:\tomcat\webapps\examples directory.
+</p>
+
+<p>
+Configuring the redirector is somewhat harder, you will need to specify the exact
+URL-Path pattern(s) which you want Tomcat to handle (usually only JSP files and servlets).
+This requires a change to the uriworkermap.properties :
+
+<div class="example"><pre>
+ For the examples context it requires to replace the following line
+ /examples/*=defworker
+ with the following two lines
+ /examples/*.jsp=defworker
+ /examples/servlet/*=defworker
+</pre></div>
+</p>
+
+<p>
+As you can see the second configuration is more explicit, it actually instruct the redirector
+to redirect only requests to resources under /examples/servlet/ and resources under /examples/
+whose name ends with .jsp.
+</p>
+
+<p>
+You can even be more explicit and provide lines such as:
+
+<div class="example"><pre>
+ /example/servletname=defworker
+</pre></div>
+</p>
+
+<p>
+that instructs the redirector to redirect all requests whose URL-path matches the leading string "/example/servletname"
+to the worker named defworker.

+<p>Once again, be aware that by allowing IIS to access the content of your Tomcat context directly, you are
+potentially bypassing Tomcat's protection of that content. You should thus make sure to protect this content
+at the IIS level if needed, by using the corresponding IIS management console functions.
+</p>
+<p>
+In particular, each servlet application (context) has a special directory named WEB-INF,
+which contains sensitive configuration data and Java classes, and which should always be kept hidden from web users.
+Using the IIS management console it is possible to protect the WEB-INF directory from user access, but considering that
+this is a general requirement, and considering that it is easy to forget to implement this protection
+at the IIS level, the redirector plugin does it automatically for you, and it will reject any request
+which contains WEB-INF in its URL-path.

+<p>
+Sometimes you may want to serve different contexts with different Tomcat processes
+(for example to spread the load among different machines).
+To achieve such a goal you will need to define several workers and assign each context to its own worker.
+</p>
+<p>
+Defining additional workers is done in the workers.properties file. This file includes two types of entries:
+</p>
+
+<p>
+<div class="example"><pre>
+ # An entry that lists all the workers defined
+ worker.list=worker1, worker2
+ # Entries that define the host and port associated with each of these workers
+ worker.worker1.host=localhost
+ worker.worker1.port=8009
+ worker.worker1.type=ajp13
+ worker.worker2.host=otherhost
+ worker.worker2.port=8009
+ worker.worker2.type=ajp13
+</pre></div>
+</p>
+
+<p>
+The above example defined two workers, now we can use these workers to serve two different contexts
+each with its own worker:
+<div class="example"><pre>
+ example uriworkermap.properties fragment
+ /examples/*=worker1
+ /webpages/*=worker2
+</pre></div>
+</p>
+
+<p>
+As you can see the <b>examples</b> context is served by <b>worker1</b> while the
+<b>webpages</b> context is served by <b>worker2</b>.

+</p>
+
+<div class="example"><pre>
+ NameTrans fn="assign-name" from="/&lt;context name&gt;/*" name="jknsapi"

+Sometimes it is better to have Netscape serve the static pages (html, gif, jpeg etc.)
+even if these files are part of a context served by Tomcat. For example, consider the html and gif files in the examples context, there is no need to serve them from the Tomcat process, Netscape will suffice.
+</p>
+<p>
+Making Netscape serve static files that are part of the Tomcat contexts requires the following:
+</p>
+<ul>
+<li>
+Configuring Netscape to know about the Tomcat contexts
+</li>
+<li>
+Make sure that the WEB-INF directory is protected from access.
+</li>
+<li>
+Configuring Netscape to assign the NSAPI redirector only specific requests that requires JSP/Servlet handling.
+</li>
+</ul>
+
+<p>
+Adding a Tomcat context to Netscape requires the addition of a new Netscape virtual directory
+that covers the Tomcat context.
+</p>
+
+<p>
+For example, adding a /example Netscape virtual directory that
+covers the <b>c:\tomcat\webapps\examples</b> directory.
+</p>
+
+<p>
+To add a new virtual directory add the following line to your <b>obj.conf</b>:
+</p>
+
+<div class="example"><pre>
+ NameTrans fn=pfx2dir from=/examples dir="c:/tomcat/webapps/examples"
+</pre></div>
+
+<p>
+WEB-INF protection requires some explanation; Each servlet application (context) has a special directory named <b>WEB-INF</b>,
+this directory contains sensitive configurations data and Java classes and must be kept hidden from web users.
+WEB-INF can be protected by adding the following line to the PathCheck section in the default configuration object:
+</p>
+
+<div class="example"><pre>
+ PathCheck fn="deny-existence" path="*/WEB-INF/*"
+
+ This line instructs the Netscape server to reject any request with a URL that contain the path /WEB-INF/.
+</pre></div>
+
+<p>
+Configuring Netscape to assign the NSAPI redirector only specific requests is somewhat harder,
+you will need to specify the exact URL-Path pattern(s) that you want Tomcat to handle
+(usually only JSP files and servlets).
+</p>
+
+<p>
+This requires a change to NameTrans portion of <b>obj.conf</b>.
+</p>
+
+<div class="example"><pre>
+ For the examples context it requires to replace the following line:
+
+ NameTrans fn="assign-name" from="/examples/*" name="jknsapi"
+
+ with the following two lines:
+
+ NameTrans fn="assign-name" from="/examples/jsp/*.jsp" name="jknsapi"
+ NameTrans fn="assign-name" from="/examples/servlet/*" name="jknsapi"
+</pre></div>
+
+<p>
+As you can see the second configuration is more explicit, it actually instructs
+Netscape to assign the redirector with only requests to resources under
+<b>/examples/servlet/</b> and resources under <b>/examples/</b> whose name ends with <b>.jsp</b>.
+</p>
+
+<p>
+You can be even more explicit and provide lines such as:
+</p>
+
+<div class="example"><pre>
+ NameTrans fn="assign-name" from="/examples/servletname" name="jknsapi"
+
+ Instructs Netscape to assign the redirector request whose URL-Path equals /example/servletname
+</pre></div>

+Sometimes you want to serve different contexts with different Tomcat processes
+(for example to spread the load among different machines).
+To achieve such goal you will need to define several workers and assign each context with its own worker.
+</p>
+
+<p>
+Defining workers is done in <b>workers.properties</b>, this file includes two types of entries:
+</p>
+
+<div class="example"><pre>
+ #An entry that lists all the workers defined. For example:
+ worker.list=worker1,worker2
+
+ # Entries that define the host and port associated with these workers.

+ worker.worker2.host=otherhost
+ worker.worker2.port=8009
+ worker.worker2.type=ajp13
+</pre></div>
+
+<p>
+The above examples defined two workers, now we can use these workers to serve two different
+contexts each with it's own worker.
+Submitting requests to different workers is accomplished by using multiple Service directives
+in the servlet configuration Object, each with a different path pattern parameter.
+</p>
+
+<p>
+For example, if we want to submit the <b>/examples</b> context to the worker named <b>worker1</b> and the
+<b>/webpages</b> context to the worker named <b>worker2</b> we should use the following configuration:
+</p>
+
+<div class="example"><pre>
+ &lt;Object name="jknsapi"&gt;
+ ObjectType fn=force-type type=text/plain
+ Service fn="jk_service" worker="worker1" path="/examples/*"

+ Service fn="jk_service" worker="worker1"
