<p>Although it is possible to handle <a href="vhosts.html">virtual hosts

with mod_rewrite</a>, it is seldom the right way. Creating individual

<VirtualHost> blocks is almost always the right way to go. In the

almost always the right way to go. In the

event that you have an enormous number of virtual hosts, consider using

<module>mod_vhost_alias</module> to create these hosts automatically.</p>
