title: How to disable routing in Symfony2 for certain paths/urls
body: <p>I would like to call a php file directly from javascript in my SF2 application without routing/controllers.</p>
  
  <p>The reason therefore is, that an external js framework (dhtmlx) has to call "<code>generate.php</code>" to produce an excel report. I put the <code>generate.php</code> under "<code>vendors/dhtmlx/generate.php</code>".</p>
  
  <p>How can I call the generate.php file without a route?</p>
  
  <p>I could implement a route to this file, but then the file is no controller object...</p>
