| <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> |
| |
| <div class="example"><p><code> |
| /usr/local/apache2/bin/httpd -S |
| </code></p></div> |
| |
| <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 |
| the docs for the <code class="program"><a href="../programs/httpd.html">httpd</a></code> program for |
| other command line options)</p> |
