<description>Provides for "trailing slash" redirects and
serving directory index files.</description>
<status>Base</status>
<sourcefile>mod_dir.c</sourcefile>
<identifier>dir_module</identifier>
<summary>
<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 <directive module="mod_dir"
>DirectoryIndex</directive> directive sets the
name of this file. This is controlled by
<module>mod_dir</module>.</li>
<li>Otherwise, a listing generated by the server. This is
provided by <module>mod_autoindex</module>.</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 <module>mod_dir</module> issues a redirect to
<code>http://servername/foo/dirname/</code>.</p>

<usage>
<p>The <directive>DirectoryIndex</directive> 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 a directory
name. <em>Local-url</em> 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>
<example><title>Example</title>
DirectoryIndex index.html
</example>
<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>
<example>DirectoryIndex index.html index.txt /cgi-bin/index.pl</example>
<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>
