+<h3>Summary</h3>
+
+ <p>The index of a directory can come from one of two sources:</p>
+
+ <ul>
+ <li>A file written by the user, typically called
+ <code>index.html</code>. The <code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> directive sets the
+ name of this file. This is controlled by
+ <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code>.</li>
+
+ <li>Otherwise, a listing generated by the server. This is
+ provided by <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code>.</li>
+ </ul>
+ <p>The two functions are separated so that you can completely
+ remove (or replace) automatic index generation should you want
+ to.</p>
+
+ <p>A "trailing slash" redirect is issued when the server
+ receives a request for a URL
+ <code>http://servername/foo/dirname</code> where
+ <code>dirname</code> is a directory. Directories require a
+ trailing slash, so <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> issues a redirect to
+ <code>http://servername/foo/dirname/</code>.</p>

+ <p>The <code class="directive">DirectoryCheckHandler</code> directive determines
+ whether <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> should check for directory indexes or
+ add trailing slashes when some other handler has been configured for
+ the current URL. Handlers can be set by directives such as
+ <code class="directive"><a href="../mod/core.html#sethandler">SetHandler</a></code> or by other modules,
+ such as <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code> during per-directory substitutions.
+ </p>
+
+ <p> In releases prior to 2.4, this module did not take any action if any
+ other handler was configured for a URL. This allows directory indexes to
+ be served even when a <code class="directive">SetHandler</code> directive is
+ specified for an entire directory, but it can also result in some conflicts
+ with modules such as <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>.</p>

+ <p>The <code class="directive">DirectoryIndex</code> directive sets the

+ of the directory by specifying a / at the end of the directory
+ name. <var>Local-url</var> is the (%-encoded) URL of a document on
+ the server relative to the requested directory; it is usually the
+ name of a file in the directory. Several URLs may be given, in
+ which case the server will return the first one that it finds. If
+ none of the resources exist and the <code>Indexes</code> option is
+ set, the server will generate its own listing of the
+ directory.</p>
+
+ <div class="example"><h3>Example</h3><pre class="prettyprint lang-config">DirectoryIndex index.html</pre>

+ directory;</p>
+
+ <pre class="prettyprint lang-config">DirectoryIndex index.html index.txt /cgi-bin/index.pl</pre>

+
+ <p>would cause the CGI script <code>/cgi-bin/index.pl</code> to be

+ existed in a directory.</p>

+ as well.</p>
+

+ directives within the <a href="../sections.html"><em>same context</em></a> will add

+ <p>The <code class="directive">DirectorySlash</code> directive determines whether
+ <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> should fixup URLs pointing to a directory or
+ not.</p>
+
+ <p>Typically if a user requests a resource without a trailing slash, which
+ points to a directory, <code class="module"><a href="../mod/mod_dir.html">mod_dir</a></code> redirects him to the same
+ resource, but <em>with</em> trailing slash for some good reasons:</p>
+
+ <ul>
+ <li>The user is finally requesting the canonical URL of the resource</li>
+ <li><code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code> works correctly. Since it doesn't emit
+ the path in the link, it would point to the wrong path.</li>
+ <li><code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> will be evaluated
+ <em>only</em> for directories requested with trailing slash.</li>
+ <li>Relative URL references inside html pages will work correctly.</li>
+ </ul>
+
+ <p>If you don't want this effect <em>and</em> the reasons above don't
+ apply to you, you can turn off the redirect as shown below. However,
+ be aware that there are possible security implications to doing
+ this.</p>
+
+ <pre class="prettyprint lang-config"># see security warning below!
+&lt;Location "/some/path"&gt;
+ DirectorySlash Off
+ SetHandler some-handler
+&lt;/Location&gt;</pre>
+
+
+ <div class="warning"><h3>Security Warning</h3>
+ <p>Turning off the trailing slash redirect may result in an information
+ disclosure. Consider a situation where <code class="module"><a href="../mod/mod_autoindex.html">mod_autoindex</a></code> is
+ active (<code>Options +Indexes</code>) and <code class="directive"><a href="#directoryindex">DirectoryIndex</a></code> is set to a valid resource (say,
+ <code>index.html</code>) and there's no other special handler defined for
+ that URL. In this case a request with a trailing slash would show the
+ <code>index.html</code> file. <strong>But a request without trailing slash
+ would list the directory contents</strong>.</p>
+ </div>
+ <p>Also note that some browsers may erroneously change POST requests into GET
+ (thus discarding POST data) when a redirect is issued.</p>

+ <p>Use this to set a handler for any URL that doesn't map to anything
+ in your filesystem, and would otherwise return HTTP 404 (Not Found).
+ For example</p>
+ <pre class="prettyprint lang-config">FallbackResource /not-404.php</pre>
+
+ <p>will cause requests for non-existent files to be handled by
+ <code>not-404.php</code>, while requests for files that exist
+ are unaffected.</p>
+ <p>It is frequently desirable to have a single file or resource
+ handle all requests to a particular directory, except those requests
+ that correspond to an existing file or script. This is often
+ referred to as a 'front controller.'</p>
+ <p>In earlier versions of httpd, this effect typically required
+ <code class="module"><a href="../mod/mod_rewrite.html">mod_rewrite</a></code>, and the use of the <code>-f</code> and
+ <code>-d</code> tests for file and directory existence. This now
+ requires only one line of configuration.</p>
+ <pre class="prettyprint lang-config">FallbackResource /index.php</pre>
+
+ <p>Existing files, such as images, css files, and so on, will be
+ served normally.</p>
+ <p>Use the <code>disabled</code> argument to disable that feature
+ if inheritance from a parent directory is not desired.</p>
+ <p>In a sub-URI, such as <em>http://example.com/blog/</em> this
+ <em>sub-URI</em> has to be supplied as <var>local-url</var>:</p>
+ <pre class="prettyprint lang-config">&lt;Directory "/web/example.com/htdocs/blog"&gt;
+ FallbackResource /blog/index.php
+&lt;/Directory&gt;
+&lt;Directory "/web/example.com/htdocs/blog/images"&gt;
+ FallbackResource disabled
+&lt;/Directory&gt;</pre>
+
+ <p>A fallback handler (in the above case, <code>/blog/index.php</code>)
+ can access the original requested URL via the server variable
+ <code>REQUEST_URI</code>. For example, to access this variable in PHP,
+ use <code>$_SERVER['REQUEST_URI']</code>.</p>
