Hi There.

I have to send a query string from the front-end through to a SAP Business Connector in order to retrieve xml based results. The connection works fine but I need to send through a username and password for authentication. Please see the code below and assist where possible.

XML

var request2 = (HttpWebRequest)WebRequest.Create("http://IPADDRESS/invoke/Get/cs_GetTest/!?$xmldata=<ZVIN>PARAM</ZVIN>");

request2.Credentials = new NetworkCredential("USERNAME", "PASSWORD");
           

HttpWebResponse resp = (HttpWebResponse)request2.GetResponse();
           

StreamReader respStream = new StreamReader(resp.GetResponseStream());
           

string xmlFileString = respStream.ReadToEnd();
           

XmlDocument doc = new XmlDocument();
           

doc.LoadXml(xmlFileString);

           
respStream.Close();

Uri requestUri = null;
              Uri.TryCreate((linkUrl), UriKind.Absolute, out requestUri);
              NetworkCredential nc = new NetworkCredential(username, password);
              CredentialCache cache = new CredentialCache();
              cache.Add(requestUri, "Basic", nc);
              cache.Add(new Uri(linkUrl), "NTLM", new NetworkCredential("", ""));

              // Requesting query string
              HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(requestUri);
              request.Credentials = cache;

              // Getting response from WebRequest
              request.Method = WebRequestMethods.Http.Get;
              HttpWebResponse response = (HttpWebResponse)request.GetResponse();
              StreamReader respStream = new StreamReader(response.GetResponseStream());
