                string strIPAddress = Request.UserHostAddress.ToString(); 
                strIPAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"]; 
                if (strIPAddress == null || strIPAddress == "") 
                    strIPAddress = Request.ServerVariables["REMOTE_ADDR"].ToString();
