There's also a great tool by Microsoft[1] (now there's an oxymoron for you :-)) called Fiddler[2] which is basically a proxy server that sits on your local machine and lets you inspect all the HTTP traffic (as well as build your own requests). The only major drawback is that since it's a separate proxy and not a browser plug-in, it can't spy on HTTPS.
