I got stuck at this line:

string sessionKey = Session["Facebook_session_key"] as String;

There is no parameter Facebook_session_key in the session I get, as a mather of fact there are no parameters at all in the session.
I always get null when calling:

string authToken = Request.QueryString["auth_token"];

string authToken = Request.QueryString["Facebook_userId"];
