  Hi

  Has anyone ever came across this problem before, the code was working ok this morning, but now it not and nothing has changed.

  Here is some test code

  string UserData = Ret.ToString();
  
                          FormsAuthenticationTicket objTestForCookiesTicket;
                          HttpCookie objTestForCookiesCookie;
                          objTestForCookiesTicket = new FormsAuthenticationTicket(1,
                          strEmail,
                          DateTime.Now,
                          DateTime.Now.AddMinutes(120),
                          true,
                          UserData);
                          objTestForCookiesCookie = new HttpCookie(".ASPXAUTH");
                          objTestForCookiesCookie.Value = FormsAuthentication.Encrypt(objTestForCookiesTicket);
                          objTestForCookiesCookie.Expires = objTestForCookiesTicket.Expiration;
                          Response.Cookies.Add(objTestForCookiesCookie);
                         
                          Response.Redirect("Test.aspx");
  
  ############
  
   string CartID;
      protected void Page_Load(object sender, EventArgs e)
      {
      FormsIdentity objTestForCookiesCookie;
     
          objTestForCookiesCookie = (FormsIdentity)User.Identity;
          CartID = objTestForCookiesCookie.Ticket.UserData.ToString();
          Response.Write("Test " + " " + CartID);
         
  
      }

  Any help on this would be appreciated

  Hi

  To get the FormsIdentity I feel you need to have been authenticated. This thread might help
