    protected void lnkresponse_click(object sender, eventargs e)     {         try         {             session["idticket"] = hfidticket.value;              response.redirect("~/forms/ticketchat.aspx");         }         catch (exception)         {              throw;         }     } 

response.redirect throws system.threading.threadabortexception exception.

try using overload, response.redirect(string url, bool endresponse) passes false endresponse parameter suppress internal call response.end.

response.redirect ("~/forms/ticketchat.aspx", false);
