+<h3>Summary</h3>
+
+ <p>The files in the <code>modules/examples</code> directory
+ under the Apache distribution directory tree are provided as an
+ example to those that wish to write modules that use the Apache
+ API.</p>
+
+ <p>The main file is <code>mod_example_hooks.c</code>, which
+ illustrates all the different callback mechanisms and call
+ syntaxes. By no means does an add-on module need to include
+ routines for all of the callbacks - quite the contrary!</p>
+
+ <p>The example module is an actual working module. If you link
+ it into your server, enable the "example-hooks-handler" handler for a
+ location, and then browse to that location, you will see a
+ display of some of the tracing the example module did as the
+ various callbacks were made.</p>

+<h2><a name="compiling" id="compiling">Compiling the example_hooks module</a></h2>
+
+ <p>To include the example_hooks module in your server, follow the
+ steps below:</p>
+
+ <ol>
+ <li>
+ Run <code class="program"><a href="../programs/configure.html">configure</a></code> with <code>--enable-example-hooks</code>
+ option.</li>
+
+ <li>Make the server (run "<code>make</code>").</li>
+ </ol>
+
+ <p>To add another module of your own:</p>
+
+ <ol class="up-A">
+ <li><code>cp modules/examples/mod_example_hooks.c
+ modules/new_module/<em>mod_myexample.c</em></code></li>
+
+ <li>Modify the file.</li>
+
+ <li>Create <code>modules/new_module/config.m4</code>.
+ <ol>
+ <li>Add <code>APACHE_MODPATH_INIT(new_module)</code>.</li>
+ <li>Copy APACHE_MODULE line with "example_hooks" from
+ <code>modules/examples/config.m4</code>.</li>
+ <li>Replace the first argument "example_hooks" with <em>myexample</em>.</li>
+ <li>Replace the second argument with brief description of your module.
+ It will be used in <code>configure --help</code>.</li>
+ <li>If your module needs additional C compiler flags, linker flags or
+ libraries, add them to CFLAGS, LDFLAGS and LIBS accordingly.
+ See other <code>config.m4</code> files in modules directory for
+ examples.</li>
+ <li>Add <code>APACHE_MODPATH_FINISH</code>.</li>
+ </ol>
+ </li>
+
+ <li>Create <code>module/new_module/Makefile.in</code>.
+ If your module doesn't need special build instructions,
+ all you need to have in that file is
+ <code>include $(top_srcdir)/build/special.mk</code>.</li>
+
+ <li>Run ./buildconf from the top-level directory.</li>
+
+ <li>Build the server with --enable-myexample</li>
+
+ </ol>

+<h2><a name="using" id="using">Using the <code>mod_example_hooks</code> Module</a></h2>
+
+ <p>To activate the example_hooks module, include a block similar to
+ the following in your <code>httpd.conf</code> file:</p>
+<pre class="prettyprint lang-config">&lt;Location "/example-hooks-info"&gt;
+ SetHandler example-hooks-handler
+&lt;/Location&gt;</pre>
+
+
+ <p>As an alternative, you can put the following into a <a href="core.html#accessfilename"><code>.htaccess</code></a> file
+ and then request the file "test.example" from that location:</p>
+<pre class="prettyprint lang-config">AddHandler example-hooks-handler ".example"</pre>
+
+
+ <p>After reloading/restarting your server, you should be able
+ to browse to this location and see the brief display mentioned
+ earlier.</p>
+</div>
+<div class="top"><a href="#page-header"><img alt="top" src="../images/up.gif" /></a></div>
+<div class="directive-section"><h2><a name="Example" id="Example">Example</a> <a name="example" id="example">Directive</a></h2>

+</table>
+ <p>The <code class="directive">Example</code> directive just sets a demonstration
+ flag which the example module's content handler displays. It
+ takes no arguments. If you browse to an URL to which the
+ example-hooks content-handler applies, you will get a display of the
+ routines within the module and how and in what order they were
+ called to service the document request. The effect of this
+ directive one can observe under the point "<code>Example
+ directive declared here: YES/NO</code>".</p>
