title: Symfony2 disable cache for a specific bundle or route
body: <p>I have an issue with <em>Sonata Admin</em> Bundle that deleting (and maybe something else??) doesn't work when caching is on. It only works properly if I remove <code>$kernel = new AppCache($kernel);</code> from <code>app.php</code>. </p>
  
  <p>How can I deactivate caching for <em>Sonata Admin</em>?</p>
