title: Facebook Invite to URL of application not application home page
body: <p>Hi I am creating a Facebook Picture Design application </p>
  
  <p>When a user A will go to application, then he can take part in group competition and can invite other friends to join his team to improve his drawing. User A will create a drawing and his invited friends can join and improve his drawing.</p>
  
  <p>Now the question is if user will send normal invitation (method: apprequest) to his friends. How his friends will redirected to his drawing page after facebook auth. </p>
  
  <p>Ex: user's A drawing URL:
    app.facebook.com/art/drawing/1</p>
  
  <p>and respectivily for other users
    app.facebook.com/art/drawing/2
    app.facebook.com/art/drawing/3 ..... and so on..</p>
  
  <p>Users a drawing page is at controller drawing/1 for invited user after auth can be redirected to app.facebook.com/art/drawing/1</p>
