6a7d71eb77725eb1b1091a94289696ab07946c7bslive <li>A file written by the user, typically called

6a7d71eb77725eb1b1091a94289696ab07946c7bslive <code>index.html</code>. The <directive module="mod_dir"

6a7d71eb77725eb1b1091a94289696ab07946c7bslive >DirectoryIndex</directive> directive sets the

6a7d71eb77725eb1b1091a94289696ab07946c7bslive name of this file. This is controlled by

6a7d71eb77725eb1b1091a94289696ab07946c7bslive <p>The <directive>DirectoryIndex</directive> directive sets the

1887c0b8ceab2c8d64a1e5b3aa512e77b86b49fayoshiki of the directory by specifying a / at the end of the directory

f5cbf3a7818c08d2f19c04fdf4f47257eea7d3c6nd name. <var>Local-url</var> is the (%-encoded) URL of a document on

6a7d71eb77725eb1b1091a94289696ab07946c7bslive the server relative to the requested directory; it is usually the

6a7d71eb77725eb1b1091a94289696ab07946c7bslive name of a file in the directory. Several URLs may be given, in

6a7d71eb77725eb1b1091a94289696ab07946c7bslive which case the server will return the first one that it finds. If

6a7d71eb77725eb1b1091a94289696ab07946c7bslive none of the resources exist and the <code>Indexes</code> option is

6a7d71eb77725eb1b1091a94289696ab07946c7bslive set, the server will generate its own listing of the

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <p>The <directive>DirectorySlash</directive> directive determines, whether

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <module>mod_dir</module> should fixup URLs pointing to a directory or

3b2d0dc9701458b42e573190ffe7344315d7bd31nd not.</p>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <p>Typically if a user requests a resource without a trailing slash, which

3b2d0dc9701458b42e573190ffe7344315d7bd31nd points to a directory, <module>mod_dir</module> redirects him to the same

3b2d0dc9701458b42e573190ffe7344315d7bd31nd ressource, but <em>with</em> trailing slash for some good reasons:</p>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <ul>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <li>The user is finally requesting the canonical URL of the resource</li>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <li><module>mod_autoindex</module> works correctly. Since it doesn't emit

3b2d0dc9701458b42e573190ffe7344315d7bd31nd the path in the link, it would point to the wrong path.</li>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <li><directive module="mod_dir">DirectoryIndex</directive> will be evaluated

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <em>only</em> for directories requested with trailing slash.</li>

3b2d0dc9701458b42e573190ffe7344315d7bd31nd <p>Well, if you don't want this effect <em>and</em> the reasons above don't

3b2d0dc9701458b42e573190ffe7344315d7bd31nd that URL. In this case a request with a trailing slash would show the
