title: Symfony 2 routing with an url as argument
body: <p>I've got some troubles when trying to pass an Url as argument in Symfony2.</p>
  
  <p>My routing.yml has this pattern : <code>pattern:  mark/{date}/{url}</code></p>
  
  <p>When i'm trying to go to : <code>/web/app_dev.php/mark/1307374717828/http%3A%2F%2Flocalhost%2Fweb%2Fapp_dev.php%2Fhome%2F</code></p>
  
  <p>I've got a not found page, it seems that it doesn't look to symfony because I haven't the problem of "route not matching".</p>
  
  <p>So how to pass an url as an argument ?</p>
