| to blue, show HTTP headers, etc.), and is very modular. Well worth a look.

Proxy 4 will also show the headers, but it won't do filtering (yet).
The problem for this purpose is that both proxy3 and proxy4 change
the headers slightly, and if you're trying to find out *exactly* what
goes on between browsers and servers, you don't want that changed
behavior.  Also, I believe Netscape (and maybe IE) will send slightly
different headers to a proxy than they will to the server.  :-(
