Virtual hosts can be "<a href="ip-based.html">IP-based</a>", meaning that you have a 38 different IP address for every web site, or "<a href="name-based.html">name-based</a>", meaning that you have 39 multiple names running on each IP address. The fact that they 40 are running on the same physical server is not apparent to the 41 end user.</p> 42 43 <p>Apache was one of the first servers to support IP-based 44 virtual hosts right out of the box. Versions 1.1 and later of 45 Apache support both IP-based and name-based virtual hosts 46 (vhosts). The latter variant of virtual hosts is sometimes also 47 called <em>host-based</em> or <em>non-IP virtual hosts</em>.</p> 48 49 <p>Below is a list of documentation pages which explain all 50 details of virtual host support in Apache HTTP Server:</p> 51 52</div> 53<div id="quickview"><ul id="toc"><li><img alt="" src="/images/down.gif" /> <a href="#support">Virtual Host Support</a></li> 54<li><img alt="" src="/images/down.gif" /> <a href="#directives">Configuration directives</a></li> 55</ul><h3>See also</h3><ul class="seealso"><li><code class="module"><a href="/mod/mod_vhost_alias.html">mod_vhost_alias</a></code></li><li><a href="name-based.html">Name-based virtual 56hosts</a></li><li><a href="ip-based.html">IP-based virtual hosts</a></li><li><a href="examples.html">Virtual host examples</a></li><li><a href="fd-limits.html">File descriptor limits</a></li><li><a href="mass.html">Mass virtual hosting</a></li><li><a href="details.html">Details of host matching</a></li></ul></div> 57<div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 58<div class="section"> 59<h2><a name="support" id="support">Virtual Host Support</a></h2> 60 61 <ul> 62 <li><a href="name-based.html">Name-based Virtual Hosts</a> (More 63 than one web site per IP address)</li> 64 <li><a href="ip-based.html">IP-based Virtual Hosts</a> (An IP 65 address for each web site)</li> 66 <li><a href="examples.html">Virtual Host examples for common 67 setups</a></li> 68 <li><a href="fd-limits.html">File Descriptor Limits</a> (or, 69 <em>Too many log files</em>)</li> 70 <li><a href="mass.html">Dynamically Configured Mass Virtual 71 Hosting</a></li> 72 <li><a href="details.html">In-Depth Discussion of Virtual Host 73 Matching</a></li> 74 </ul> 75 76</div><div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 77<div class="section"> 78<h2><a name="directives" id="directives">Configuration directives</a></h2> 79 80 <ul> 81 <li><code class="directive"><a href="/mod/core.html#virtualhost"><VirtualHost></a></code></li> 82 <li><code class="directive"><a href="/mod/core.html#servername">ServerName</a></code></li> 83 <li><code class="directive"><a href="/mod/core.html#serveralias">ServerAlias</a></code></li> 84 <li><code class="directive"><a href="/mod/core.html#serverpath">ServerPath</a></code></li> 85 </ul> 86 87 <p>If you are trying to debug your virtual host configuration, you 88 may find the Apache <code>-S</code> command line switch 89 useful.
