<h1 align="CENTER">Apache Virtual Host documentation</h1>
<p>The term <cite>Virtual Host</cite> refers to the practice of
maintaining more than one server on one machine, as
differentiated by their apparent hostname. For example, it is
often desirable for companies sharing a web server to have
their own domains, with web servers accessible as
<samp>www.company1.com</samp> and
<samp>www.company2.com</samp>, without requiring the user to
know any extra path information.</p>
<p>Apache was one of the first servers to support IP-based
virtual hosts right out of the box. Versions 1.1 and later of
Apache support both, IP-based and name-based virtual hosts
(vhosts). The latter variant of virtual hosts is sometimes also
called host-based or non-IP virtual hosts.</p>
<p>Below is a list of documentation pages which explain all
details of virtual host support in Apache version 1.3 and
later.</p>
<hr />
<h2>Virtual Host Support</h2>
<ul>
<li><a href="name-based.html">Name-based Virtual
Hosts</a></li>
<li><a href="ip-based.html">IP-based Virtual Hosts</a></li>
<li><a href="examples.html">Virtual Host examples for common
setups</a></li>
<li><a href="details.html">In-Depth Discussion of Virtual
Host Matching</a></li>
<li><a href="fd-limits.html">File Descriptor Limits</a></li>
<li><a href="mass.html">Dynamically Configured Mass Virtual
Hosting</a></li>
</ul>
<h2>Configuration directives</h2>
<ul>
<li><a
href="../mod/core.html#virtualhost"><VirtualHost></a></li>
<li><a
href="../mod/core.html#namevirtualhost">NameVirtualHost</a></li>
<li><a href="../mod/core.html#servername">ServerName</a></li>
<li><a
href="../mod/core.html#serveralias">ServerAlias</a></li>
<li><a href="../mod/core.html#serverpath">ServerPath</a></li>
</ul>
<p>Folks trying to debug their virtual host configuration may
find the Apache <code>-t -D DUMP_VHOSTS</code> command line switch
useful. It will dump out a description of how Apache parsed the
configuration file. Careful examination of the IP addresses and
server names may help uncover configuration mistakes.
