title: Symfony2 language selector
body: <p>I would like to integrate a simple HTML form allowing the user to change Symfony2 web application's language (i.e. from page en/faq go to fr/faq). How to do it in a proper way?</p>
  
  <p>I have found a nice way of doing it with Symfony but not with Symfony2: <a href="http://symfony.com/blog/play-with-the-user-language" rel="noreferrer">http://symfony.com/blog/play-with-the-user-language</a></p>
