+    <p>
+      Installing Tomcat on Windows can be done easily using the Windows
+      installer. Its interface and functionality is similar to other wizard
+      based installers, with only a few items of interest.
+    </p>
+
+    <p>
+      <ul>
+        <li><strong>Installation as a service</strong>: Tomcat will be
+            installed as a Windows service no matter what setting is selected.
+            Using the checkbox on the component page sets the service as "auto"
+            startup, so that Tomcat is automatically started when Windows
+            starts. For optimal security, the service should be run as a
+            separate user, with reduced permissions (see the Windows Services
+            administration tool and its documentation).</li>
+        <li><strong>Java location</strong>: The installer will provide a default
+            JRE to use to run the service. The installer uses the registry to
+            determine the base path of a Java 6 or later JRE, including the JRE
+            installed as part of the full JDK. When running on a 64-bit
+            operating system, the installer will first look for a 64-bit JRE and
+            only look for a 32-bit JRE if a 64-bit JRE is not found. It is not
+            mandatory to use the default JRE detected by the installer. Any
+            installed Java 6 or later JRE (32-bit or 64-bit) may be used.</li>
+        <li><strong>Tray icon</strong>: When Tomcat is run as a service, there
+            will not be any tray icon present when Tomcat is running. Note that
+            when choosing to run Tomcat at the end of installation, the tray
+            icon will be used even if Tomcat was installed as a service.</li>
+        <li>Refer to the
+            <a href="windows-service-howto.html">Windows Service HOW-TO</a>
+            for information on how to manage Tomcat as a Windows service.
+            </li>
+      </ul>
+    </p>
+
+    <p>The installer will create shortcuts allowing starting and configuring
+       Tomcat. It is important to note that the Tomcat administration web
+       application can only be used when Tomcat is running.</p>
+

+
+    <p>Tomcat can be run as a daemon using the jsvc tool from the
+       commons-daemon project. Source tarballs for jsvc are included with the
+       Tomcat binaries, and need to be compiled. Building jsvc requires
+       a C ANSI compiler (such as GCC), GNU Autoconf, and a JDK.</p>
+
+    <p>Before running the script, the <code>JAVA_HOME</code> environment
+       variable should be set to the base path of the JDK. Alternately, when
+       calling the <code>./configure</code> script, the path of the JDK may
+       be specified using the <code>--with-java</code> parameter, such as
+       <code>./configure --with-java=/usr/java</code>.</p>
+
+    <p>Using the following commands should result in a compiled jsvc binary,
+       located in the <code>$CATALINA_HOME/bin</code> folder. This assumes
+       that GNU TAR is used, and that <code>CATALINA_HOME</code> is an
+       environment variable pointing to the base path of the Tomcat
+       installation.</p>
+
+    <p>Please note that you should use the GNU make (gmake) instead of
+       the native BSD make on FreeBSD systems.</p>

+
+    <p>You may also need to specify <code>-jvm server</code> if the JVM defaults
+       to using a server VM rather than a client VM. This has been observed on
+       OSX.</p>
+
+    <p>jsvc has other useful parameters, such as <code>-user</code> which
+       causes it to switch to another user after the daemon initialization is
+       complete. This allows, for example, running Tomcat as a non privileged
+       user while still being able to use privileged ports. Note that if you
+       use this option and start Tomcat as root, you'll need to disable the
+       <code>org.apache.catalina.security.SecurityListener</code> check that
+       prevents Tomcat starting when running as root.</p>
+
+    <p><code>jsvc --help</code> will return the full jsvc usage
+       information. In particular, the <code>-debug</code> option is useful
+       to debug issues running jsvc.</p>
+
+    <p>The file <code>$CATALINA_HOME/bin/daemon.sh</code> can be used as a
+       template for starting Tomcat automatically at boot time from
+       <code>/etc/init.d</code> with jsvc.</p>
+
+    <p>Note that the Commons-Daemon JAR file must be on your runtime classpath
+       to run Tomcat in this manner.  The Commons-Daemon JAR file is in the
+       Class-Path entry of the bootstrap.jar manifest, but if you get a
+       ClassNotFoundException or a NoClassDefFoundError for a Commons-Daemon
+       class, add the Commons-Daemon JAR to the -cp argument when launching
+       jsvc.</p>

+
+<p>SSI (Server Side Includes) are directives that are placed in HTML pages,
+and evaluated on the server while the pages are being served. They let you
+add dynamically generated content to an existing HTML page, without having
+to serve the entire page via a CGI program, or other dynamic technology.
+</p>
+
+<p>Within Tomcat SSI support can be added when using Tomcat as your
+HTTP server and you require SSI support.  Typically this is done
+during development when you don't want to run a web server like Apache.</p>
+
+<p>Tomcat SSI support implements the same SSI directives as Apache.  See the
+<a href="http://httpd.apache.org/docs/howto/ssi.html#basicssidirectives">
+Apache Introduction to SSI</a> for information on using SSI directives.</p>
+
+<p>SSI support is available as a servlet and as a filter. You should use one
+or the other to provide SSI support but not both.</p>
+
+<p>Servlet based SSI support is implemented using the class
+<code>org.apache.catalina.ssi.SSIServlet</code>.  Traditionally, this servlet
+is mapped to the URL pattern "*.shtml".</p>
+
+<p>Filter based SSI support is implemented using the class
+<code>org.apache.catalina.ssi.SSIFilter</code>.  Traditionally, this filter
+is mapped to the URL pattern "*.shtml", though it can be mapped to "*" as
+it will selectively enable/disable SSI processing based on mime types.  The
+contentType init param allows you to apply SSI processing to JSP pages,
+javascript, or any other content you wish.</p>
+<p>By default SSI support is disabled in Tomcat.</p>

+<p>Server Side Includes are invoked by embedding SSI directives in an HTML document

+ comment. The directive is replaced by the results of interpreting it before sending the
+ page to the client. The general form of a directive is: </p>
+<p> <code>&lt;!--#directive [parm=value] --&gt;</code></p>
+<p>The directives are:
+<ul>
+<li>
+<strong>config</strong> - <code>&lt;!--#config timefmt="%B %Y" --&gt;</code>
+Used to set the format of dates and other items processed by SSI
+</li>
+<li>
+<strong>echo</strong> -   <code>&lt;!--#echo var="VARIABLE_NAME" --&gt;</code>
+will be replaced by the value of the variable.
+</li>
+<li>
+<strong>exec</strong> -  Used to run commands on the host system.
+</li>
+<li>
+<strong>include</strong> -  <code>&lt;!--#include virtual="file-name" --&gt;</code>
+inserts the contents
+</li>
+<li>
+<strong>flastmod</strong> - <code>&lt;!--#flastmod file="filename.shtml" --&gt;</code>
+Returns the time that a file was lost modified.
+</li>
+<li>
+<strong>fsize</strong> - <code>&lt;!--#fsize file="filename.shtml" --&gt;</code>
+Returns the size of a file.
+</li>
+<li>
+<strong>printenv</strong> - <code>&lt;!--#printenv --&gt;</code>
+Returns the list of all the defined variables.
+</li>
+<li>
+<strong>set</strong> - <code>&lt;!--#set var="foo" value="Bar" --&gt;</code>
+is used to assign a value to a user-defind variable.
+</li>
+<li>
+<strong>if elif endif else</strong> - Used to create conditional sections. For example:</li>
+<code>&lt;!--#config timefmt="%A" --&gt;<br>
+  &lt;!--#if expr="$DATE_LOCAL = /Monday/" --&gt;<br>
