| |
| <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> |

| <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. |
