title: Symfony2 The CSRF token is invalid
body: <p>I have a problem with Symfony. When I submit the <code>FOSUserBundle</code> register form on the built-in Symfony server (on the port <code>:8000</code>), it shows the error below:</p>
  
  <blockquote>
    <p>"The CSRF token is invalid. Please try to resubmit the form."</p>
  </blockquote>
  
  <p>But, when I submit form on Apache server (by <code>/web/app_dev.php/</code>), all works fine.</p>
  
  <p>Hidden token input exists in form.</p>
