I'm using HttpWebRequest and x509Certificate class to Post to another website in my server to check if it sees my client certificate:

in the response I'm getting 'No certificate was found' from the other page.

I have the client cert intalled in the LocalMachine\Personal Store. Let me know what other details you need


CODE FROM Client sending the cert:
X509Certificate cert = X509Certificate.CreateFromCertFile(@"QBClientCertDER2.cer");
              HttpWebRequest wr = (HttpWebRequest) WebRequest.Create(CheckCert.aspx);
            wr.ClientCertificates.Add(cert);                  
              wr.Method = "POST";
              wr.KeepAlive = false;
              wr.ContentType = "application/x-qbxml";
              wr.ContentLength = XMLRequest.Length;
            
              // send xml data
              StreamWriter SendStream;
            SendStream = new StreamWriter(wr.GetRequestStream());
              //SendStream.Write(byteArray,0,byteArray.Length);
            SendStream.Write(XMLRequest);
            SendStream.Flush();
              SendStream.Close();
              HttpWebResponse WebResp = (HttpWebResponse) wr.GetResponse();
              string res = "";

            
                  using (StreamReader sr = new StreamReader(WebResp.GetResponseStream()) )
                  {

                      res = sr.ReadToEnd();

                      sr.Close();

                  }

                        Output.Text = res.ToString();
                  Output.Text += cert.GetName();
                  WebResp.Close();

              }

              catch(Exception err)

              {

                  Response.Write(err.ToString() + "<br>");
             Response.Write(XMLRequest.ToString());

              }

CODE Checking the cert (CheckCert.aspx):
      Dim cs As HttpClientCertificate = Request.ClientCertificate
         If cs.IsPresent Then
             'Get the Organization (O) field from the Subject section.
             Response.Write("Cert subject: " & cs.Get("Subject O"))
         Else
             Response.Write("No certificate was found.")
         End If

I'm not sure if i wan't to sign an xml object.

Also, i think I've intalled the client cert in  local_machine\personal
and the accompanying CA in the Root folder

yes, HttpWebRequest.ClientCertificate.Add.....

any ideas. I think something is preventing HTTPWebrequest from sending the cert to the remote server.
