- <title>Apache Virtual Host documentation</title>
-
- <summary>
-
- <p>The term <cite>Virtual Host</cite> refers to the practice of
- running more than one web site (such as
- <code>www.company1.com</code> and <code>www.company2.com</code>)
- on a single machine. Virtual hosts can be "<a
- href="ip-based.html">IP-based</a>", meaning that you have a
- different IP address for every web site, or "<a
- href="name-based.html">name-based</a>", meaning that you have
- multiple names running on each IP address. The fact that they
- are running on the same physical server is not apparent to the
- end user.</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 <em>host-based</em> or <em>non-IP virtual hosts</em>.</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>

-
- <p>If you are trying to debug your virtual host configuration, you
- may find the Apache <code>-S</code> command line switch
- useful. That is, type the following command:</p>
-
- <example>
- /usr/local/apache2/bin/httpd -S
- </example>
-
- <p>This command 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. (See <a
- href="../programs/httpd.html">the docs for the httpd program</a> for
- other command line options)</p>
