HttpWebResponse response = (HttpWebResponse)request.GetResponse();
String responseString = new StreamReader(response.GetResponseStream()).ReadToEnd().Trim();

if (!String.IsNullOrEmpty(responseString) && String.Equals(responseString, "SUCCESS"))
    {
         MessageBox.Show("Login Successful.");
    }
