Connect to web site using SSL & Client Certificates

[Krishna]

Well, I got it working when running against my test server (IIS5 W2K
svr, I will attach a sample of the code at the bottom of this
message), but now I'm connecting to our client (Apache) I'm getting
the following error:

An unhandled exception of type 'System.Net.Web Exception' occurred in
system.dll

Additional information: The underlying connection was closed: Unable
to connect to the remote server.
This exception is thrown when the GetRequestStrea m() method is
called and I am using a client cert that was issued to us from their
internal CA (they are using OpenSSL).

Any help'd be much appreciated!

string certInfo = tr.ReadToEnd();

System.Diagnost ics.Debug.Write Line(certInfo);

Okey dokey, well only a little embarrassed! I didn't have the
private key for the Client Cert that our client gave us, therefor it
wasn't properly loaded in my Personal Cert store, therefor when the
connection was being negotiated it crashed... I got the full key
pair from them and voila!

Hope this helps anyone!
