        }

        string result = "";

        string strPost = "data1=" + data1+ "&data2=" + data2;

        StreamWriter myWriter = null;

        HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(url);

        objRequest.Method = "POST";

        objRequest.Timeout = 200000; // this should be greater than IIS / web server's timeout

        objRequest.ContentLength = strPost.Length;

        objRequest.ContentType = "application/x-www-form-urlencoded";

        objRequest.KeepAlive = false;

        try

        {

            myWriter = new StreamWriter(objRequest.GetRequestStream());

            myWriter.Write(strPost);

        }

        catch (Exception e)

        {

            throw new Exception(e.ToString());

        }

        finally

        {

            myWriter.Close();

        }

        HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();

        using (StreamReader sr = new StreamReader(objResponse.GetResponseStream)))

        {

            result = sr.ReadToEnd();
