  threshold on comp.infosystems.www.servers.unix.

  +        <p>Many sites map a variety of hostnames to the same content.
  +     (This differs from <a href="../vhosts/">virtual hosting</a> where
  +     different hostnames map to different content.)  For example,
  +        <code>www.example.com</code>, <code>example.com</code> and
  +        <code>www.example.net</code> may all refer to the same site.
  +     It is best to make sure that, regardless of the name clients
  +     use to access the site, they will be redirected to a single,
  +     canonical hostname.  This makes the site easier to maintain
  +     and assures that there will be only one version of the site
  +     in proxy caches and search engines.</p>
  +
  +        <p>There are two techniques to implement canonical hostnames:</p>
  +
  +        <ol>
  +       <li>Use <a href="../mod/mod_rewrite.html">mod_rewrite</a>
  +       as described in the "Canonical Hostnames" section of the
  +       <a href="rewriteguide.html">URL Rewriting Guide</a>.</li>
  +
  +       <li>Use <a href="../vhosts/name-based.html">name-based
  +       virtual hosting</a>:
  +
  +<blockquote><code>
  +NameVirtualHost *<br>
  +<br>
  +&lt;VirtualHost *&gt;<br>
  +&nbsp;&nbsp;ServerName www.example.net<br>
  +&nbsp;&nbsp;ServerAlias example.com<br>
  +&nbsp;&nbsp;Redirect permanent / http://www.example.com/<br>
  +&lt;/VirtualHost&gt;<br>

  +&lt;VirtualHost *&gt;<br>
  +&nbsp;&nbsp;ServerName www.example.com<br>
  +&nbsp;&nbsp;DocumentRoot /usr/local/apache/htdocs<br>
