Thanks. I had tried that. It would have worked, I think, but my problem turned out to be function realted instead of syntax related. Robert A hit the nail on the head: I was opening a non-proxy session and then using that handle to try and set proxy stuff, which is not allowed. I am going to have to test this on a machine that is actually using a proxy server.
