To do this you might use the + following in your configuration file:</p> + + <pre class="prettyprint lang-config">UseCanonicalName Off +VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2"</pre> + + + <p>A request for + <code>http://www.domain.example.com/directory/file.html</code> + will be satisfied by the file + <code>/usr/local/apache/vhosts/example.com/d/o/m/domain/directory/file.html</code>.</p> + + <p>A more even spread of files can be achieved by hashing from the + end of the name, for example: </p> + +<pre class="prettyprint lang-config">VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.-1/%2.-2/%2.-3/%2"</pre> + + + <p>The example request would come from + <code>/usr/local/apache/vhosts/example.com/n/i/a/domain/directory/file.html</code>.</p> + + <p>Alternatively you might use: </p> + +<pre class="prettyprint lang-config">VirtualDocumentRoot "/usr/local/apache/vhosts/%3+/%2.1/%2.2/%2.3/%2.4+"</pre> + + + <p>The example request would come from + <code>/usr/local/apache/vhosts/example.com/d/o/m/ain/directory/file.html</code>.</p> + +<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> +<pre class="prettyprint lang-config">VirtualDocumentRoot "/usr/local/apache/vhosts/%-2.0.%-1.0"</pre> + +<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>. +</p> + + <p>For IP-based virtual hosting you might use the following in + your configuration file:</p> + + <pre class="prettyprint lang-config">UseCanonicalName DNS +VirtualDocumentRootIP "/usr/local/apache/vhosts/%1/%2/%3/%4/docs" +VirtualScriptAliasIP "/usr/local/apache/vhosts/%1/%2/%3/%4/cgi-bin"</pre> + + + <p>A request for + <code>http://www.domain.example.com/directory/file.html</code> + would be satisfied by the file + <code>/usr/local/apache/vhosts/10/20/30/40/docs/directory/file.html</code> + if the IP address of <code>www.domain.example.com</code> were + 10.20.30.40.
