Easily Check HTTP Headers with this tool

We were trying to solve an annoying bug in our mod_rewrite code today and couldn't quite figure out why our server was acting the way it was. Fortunately we discovered a nifty tool (Thanks pkhach!) that allows you to view the HTTP request and response headers for any URL you like. You can even choose between HTTP/1.1 and HTTP/1.0, with and without the Host header. View HTTP Headers A reader also suggests this Firefox extension. Thanks, Eric! The best part is that both of these are much easier than messing about with Telnet.exe!
