+<p> A very common request by users is the ability to point multiple domains to multiple

+document roots without having to worry about the length or number of parts of the 
+hostname being requested. If the requested hostname is <code>sub.www.domain.example.com</code>
+ instead of simply <code>www.domain.example.com</code>, then using %3+ will result
in the document
+root being <code>/usr/local/apache/vhosts/domain.example.com/...</code> instead
of the
+intended <code>example.com</code> directory. In such cases, it can be beneficial
to use 
+the combination <code>%-2.0.%-1.0</code>, which will always yield the domain
name and the 
+tld, for example <code>example.com</code> regardless of the number of subdomains
appended 
+to the hostname. As such, one can make a configuration that will direct all first, second

+or third level subdomains to the same directory:

+<p>
+In the example above, both <code>www.example.com</code> as well as <code>www.sub.example.com</code>
+or <code>example.com</code> will all point to <code>/usr/local/apache/vhosts/example.com</code>.
