    Oh sorry, missed that. I always just use HttpWebRequest. I'm not even sure
    what the WebClient is for.

    I'd definitely go in that direction :)

    You'll have to mess with the streams yourself, but that isn't such a big
    deal.

    The WebRequest object has PreAuthenticate, not WebClient. Do you know if
    there is a way to access the underlying WebRequest object that the WebClient
    uses? I didn't see a way to do this. Should I scrap the WebClient and just
    use WebRequest?

    Thanks,
