You can modify the html pages that are sent when an error occurs.<br />
<br />
The default files are contained in the <span class="code">system</span> directory used
by the host and can be replaced with your own files.
Different <a href="virtualhosts.html">Virtual Hosts</a> can use different error
files.<br />
<br />
The pages must not contain any references to other documents in the system directory.
<br />
Every request to <span class="code"/sys></span> will be mapped to the system directory. So a request to <a href="http://sys/file.html"http://sys/file.html></a> will send the file <span class="code">file.html</span> contained in the <span class="code">system</span> directory for the virtual host.
