title: Changing Symfony Default Route Class
body: <p>In symfony's routing.yml, you can assign a different class to be used in place of sfRoute.
  i.e. </p>
  
  <pre><code>routeName:
   url: /url/blah
   class: sfRequestRoute
   param: {module: mymod, action: myaction}
   requirements:
     sf_method: [get]
  </code></pre>
  
  <p>However, I would like to be able to change the default class so that all routes use sfRequestRoute unless I specify otherwise.  Is there a way to do this?  I am using Symfony 1.4</p>
