Hi

I am using WebRequest object to access a https URL through a proxy:

string Url = "https://www.verisign.com";
WebProxy proxy = new WebProxy("http://proxyserver.domain.com:80",true);
proxy.Credentials=System.Net.CredentialCache.DefaultCredentials;
WebRequest req =WebRequest.Create(Url);
req.Method="GET";
req.Proxy= proxy;
result = req.GetResponse();

The proxy server requires NTLM authentication.

This code works fine if
(a) The URL is an http site
(b) the URL is a local https site (therefore bypassing the proxy)

but doesnt work where proxy authentication is required for an external
https URL.

I can access the https site fine through the proxy in IE so the proxy
and authentication are clearly working OK.

I have read another post that indicated this was an issue in .NET
Compact Framework
(http://www.dotnet247.com/247reference/msgs/51/255270.aspx) - does
anybody know if this is also the case with .NET on W2003?

Or is there something that I am missing?

Any help gratefully received.
