  31     <p>The term <cite>Virtual Host</cite> refers to the practice of
  32     running more than one web site (such as
  33     <code>www.company1.com</code> and <code>www.company2.com</code>)
  34     on a single machine. Virtual hosts can be "<a href="ip-based.html">IP-based</a>", meaning that you have a
  35     different IP address for every web site, or "<a href="name-based.html">name-based</a>", meaning that you have
  36     multiple names running on each IP address. The fact that they
  37     are running on the same physical server is not apparent to the
  38     end user.</p>
  39
  40     <p>Apache was one of the first servers to support IP-based
  41     virtual hosts right out of the box. Versions 1.1 and later of
  42     Apache support both IP-based and name-based virtual hosts
  43     (vhosts). The latter variant of virtual hosts is sometimes also
  44     called <em>host-based</em> or <em>non-IP virtual hosts</em>.</p>
  45
  46     <p>Below is a list of documentation pages which explain all
  47     details of virtual host support in Apache version 1.3 and
  48     later.</p>

  86     <p>If you are trying to debug your virtual host configuration, you
  87     may find the Apache <code>-S</code> command line switch
  88     useful. That is, type the following command:</p>
  89
  90     <div class="example"><p><code>
  91     /usr/local/apache2/bin/httpd -S
  92     </code></p></div>
  93
  94     <p>This command will dump out a description of how Apache parsed
  95     the configuration file. Careful examination of the IP addresses and
  96     server names may help uncover configuration mistakes. (See
  97     the docs for the <code class="program"><a href="../programs/httpd.html">httpd</a></code> program for
  98     other command line options)</p>
