Headers - How to check

I have 3 url's that I would like to check to see what headers are sent on request. Anyone know of any tools that will let me see the server response?

should be 200

should be 404

should be 301

Edit: sorry, lol ignore this... just found http://www.seoconsultants.com/tools/headers.asp and it seems to do the trick for me :|

firefox has a toolbar/plugin called "live http headers" which is neat to watch. check it out.

Very cool add-on! Installed.

Thanks Brian
