24
25    <p>The term <cite>Virtual Host</cite> refers to the practice of
26    maintaining more than one server on one machine, as
27    differentiated by their apparent hostname. For example, it is
28    often desirable for companies sharing a web server to have
29    their own domains, with web servers accessible as
30    <samp>www.company1.com</samp> and
31    <samp>www.company2.com</samp>, without requiring the user to
32    know any extra path information.</p>
33
34    <p>Apache was one of the first servers to support IP-based
35    virtual hosts right out of the box. Versions 1.1 and later of
36    Apache support both, IP-based and name-based virtual hosts
37    (vhosts). The latter variant of virtual hosts is sometimes also
38    called host-based or non-IP virtual hosts.</p>
39
40    <p>Below is a list of documentation pages which explain all
41    details of virtual host support in Apache version 1.3 and
42    later.</p>

81
82    <p>Folks trying to debug their virtual host configuration may
83    find the Apache <code>-S</code> command line switch useful. It
84    will dump out a description of how Apache parsed the
85    configuration file. Careful examination of the IP addresses and
86    server names may help uncover configuration mistakes.
