What is the easiest way, in Windows, to sniff the HTTP (and HTTPS) requests and responses back from the server for an application that won't let you tell it to use a proxy? [more inside]

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?
