I'm trying to get my application (VB, but that doesn't matter) to connect to the internet and support proxy servers that require a username and password. The former is easy, the latter not. What I'm doing is sending Proxy-Authorization: Basic [authentication] in the header (where [authentication] is "username:password" base64 encoded) with each request. However the proxy server keeps reporting error 407 (authentication required). I've read the RFC's, I've read google groups but I have no idea what I'm doing wrong. Any ideas?
