<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">DirectoryIndex</code> directive sets the
list of resources to look for, when the client requests an index
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><p><code>
DirectoryIndex index.html
</code></p></div>
<p>then a request for <code>http://myserver/docs/</code> would
return <code>http://myserver/docs/index.html</code> if it
exists, or would list the directory if it did not.</p>
<p>Note that the documents do not need to be relative to the
directory;</p>
<div class="example"><p><code>
DirectoryIndex index.html index.txt /cgi-bin/index.pl
</code></p></div>
<p>would cause the CGI script <code>/cgi-bin/index.pl</code> to be
executed if neither <code>index.html</code> or <code>index.txt</code>
existed in a directory.</p>

<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>Well, if you don't want this effect <em>and</em> the reasons above don't
apply to you, you can turn off the redirect with:</p>
<div class="example"><p><code>
# see security warning below!<br />
<Location /some/path><br />
<span class="indent">
DirectorySlash Off<br />
SetHandler some-handler<br />
</span>
</Location>
</code></p></div>
<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>
