Hi all,

I need to post a data to a secure site that looks like https://abcdef.asp" and that site returns response depends upon what you sent to that using asp.net.

I used the following code but, I got some error like "The underlying connection was closed. Could not established trust realitionship for the SSL/TLS secure channel".

My code:

private string TransferXML(string strXML)

{

                string TxRequest = strXML;

                WebRequest req = null;
                WebResponse rps = null;
string strUrlToTravelers = ConfigurationManager.AppSettings["urlToTravelers"].ToString();                         
                req = WebRequest.Create(strUrlToTravelers);
              
                req.Method = "POST";
                req.ContentType = "application/x-www-form-urlencoded";               

                StreamWriter wr = new StreamWriter(req.GetRequestStream());
                wr.WriteLine(TxRequest);
                wr.Close();
                rps = req.GetResponse();              

                if (!req.Equals(null))
                {
                    req.GetRequestStream().Close();
                }
                if (!rps.Equals(null))
                {
                    HttpWebRequest httpWebRequest = (HttpWebRequest)WebRequest.Create(strUrlToTravelers);
                    //httpWebRequest.KeepAlive = false;
                    HttpWebResponse httpWebResponse = (HttpWebResponse)(httpWebRequest.GetResponse());
                }

                Stream receiveStream = rps.GetResponseStream();
                Encoding encode = System.Text.Encoding.GetEncoding("utf-8");
                StreamReader readStream = new StreamReader(receiveStream, encode);
                TxRequest = readStream.ReadToEnd();
                readStream.Close();
                rps.Close();

            }
            catch(Exception ex)
            {
                Response.Write(ex.Message.ToString());
            }
            finally
            {
            }

            return TxRequest;

}

After all I could not ge the value from secure connection.

I should be happy if any one answer to my question as soon as possible.

Thanks
