title: Facebook access Token with longer expiration
body: <p>I am trying to follow <a href="http://developers.facebook.com/docs/offline-access-deprecation/#extend_token" rel="noreferrer">this tutorial</a> on getting a token with longer expiration time  . The Facebook connect is done on the client side (Js sdk). The steps I take are:</p>
  
  <ul>
  <li>enabled 'deprecate offline_access' on my app settings page</li>
  <li>retreive the access_token as normal</li>
  <li>curl "<a href="https://graph.facebook.com/oauth/access_token" rel="noreferrer">https://graph.facebook.com/oauth/access_token</a>?<br>
      client_id=APP_ID&amp;
      client_secret=APP_SECRET&amp;
      grant_type=fb_exchange_token&amp;
      fb_exchange_token=access_token"</li>
  </ul>
  
  <p>This always returns the same exact same access token with expiration of 2 hours, shouldn't it return a token (same or not as access_token) that is valid 60 days ?</p>
  
  <p>Thanks</p>
