06ba4a61654b3763ad65f52283832ebf058fdf1cslive <li>A file written by the user, typically called

06ba4a61654b3763ad65f52283832ebf058fdf1cslive name of this file. This is controlled by

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
