title: Symfony2 everything cached on dev?
body: <p>If I change something in a controller I have to wait like 40 seconds until i see the changes. Seems like Symfony is caching but i thought it is not when im using web/app_dev.php/ ??</p>
  
  <p>Did i do something wrong with the Symfony installation??</p>
  
  <p>I googled for this but i only find to put following into config_dev.yml</p>
  
  <pre><code>twig:
      cache:  false
  </code></pre>
  
  <p>And now when i change something within template files it is shown directly. But when i change something in the controller i still have to wait 40 seconds... :(</p>
