Al: NTLM Authentication with HttpClient

[jcooper01]

We need to be able to do Basic authentication and NTLM authentication with the HttpClient. I don't see a way to do that. I suppose that for Basic, we could manually construct and add the header ourselves, but that's not practical with NTLM.

[ajkauffmann]

Actually, you can do Basic Authentication with HttpClient. Here is how:

  RequestMessage : HttpRequestMessage;
  Headers : HttpHeaders;
  TempBlob : Record TempBlob temporary;
begin
  RequestMessage.GetHeaders(Headers);
  AuthText := StrSubstNo('%1:%2',Parameters.UserName,Parameters.Password);
  TempBlob.WriteAsText(AuthText,TextEncoding::Windows);
  Headers.Add('Authorization', StrSubstNo('Basic %1',TempBlob.ToBase64String()));
end

Right. That's what I meant by generating the header manually. However, we also need NTLM support.

It's on our backlog, no timeframe yet.
