title: Apache: VirtualHost with [PHP|Python|Ruby] support
body: <p>I am experimenting with several languages (Python, Ruby...), and I would like to know if there is a way <strong>to optimize</strong> my Apache Server to load 
  <strong>certain</strong> modules <strong>only</strong> in <strong>certain</strong> VirtualHost, for instance: </p>
  
  <pre><code>http://myapp1 &lt;- just with Ruby support 
  http://myapp2 &lt;- just with Python support
  http://myapp3 &lt;- just with Php support
  ...
  </code></pre>
  
  <p>Thanks.</p>
