Virtual hosts can be "<a href="ip-based.html">IP-based</a>", meaning that you have a 39 different IP address for every web site, or "<a href="name-based.html">name-based</a>", meaning that you have 40 multiple names running on each IP address. The fact that they 41 are running on the same physical server is not apparent to the 42 end user.</p> 43 44 <p>Apache was one of the first servers to support IP-based 45 virtual hosts right out of the box. Versions 1.1 and later of 46 Apache support both IP-based and name-based virtual hosts 47 (vhosts). The latter variant of virtual hosts is sometimes also 48 called <em>host-based</em> or <em>non-IP virtual hosts</em>.</p> 49 50 <p>Below is a list of documentation pages which explain all 51 details of virtual host support in Apache HTTP Server:</p> 52 53</div> 54<div id="quickview"><ul id="toc"><li><img alt="" src="/images/down.gif" /> <a href="#support">Virtual Host Support</a></li> 55<li><img alt="" src="/images/down.gif" /> <a href="#directives">Configuration directives</a></li> 56</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 57hosts</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> 58<div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 59<div class="section"> 60<h2><a name="support" id="support">Virtual Host Support</a></h2> 61 62 <ul> 63 <li><a href="name-based.html">Name-based Virtual Hosts</a> (More 64 than one web site per IP address)</li> 65 <li><a href="ip-based.html">IP-based Virtual Hosts</a> (An IP 66 address for each web site)</li> 67 <li><a href="examples.html">Virtual Host examples for common 68 setups</a></li> 69 <li><a href="fd-limits.html">File Descriptor Limits</a> (or, 70 <em>Too many log files</em>)</li> 71 <li><a href="mass.html">Dynamically Configured Mass Virtual 72 Hosting</a></li> 73 <li><a href="details.html">In-Depth Discussion of Virtual Host 74 Matching</a></li> 75 </ul> 76 77</div><div class="top"><a href="#page-header"><img alt="top" src="/images/up.gif" /></a></div> 78<div class="section"> 79<h2><a name="directives" id="directives">Configuration directives</a></h2> 80 81 <ul> 82 <li><code class="directive"><a href="/mod/core.html#namevirtualhost">NameVirtualHost</a></code></li> 83 <li><code class="directive"><a href="/mod/core.html#virtualhost"><VirtualHost></a></code></li> 84 <li><code class="directive"><a href="/mod/core.html#servername">ServerName</a></code></li> 85 <li><code class="directive"><a href="/mod/core.html#serveralias">ServerAlias</a></code></li> 86 <li><code class="directive"><a href="/mod/core.html#serverpath">ServerPath</a></code></li> 87 </ul> 88 89 <p>If you are trying to debug your virtual host configuration, you 90 may find the Apache <code>-S</code> command line switch 91 useful.
