HURL: Great Tool for Testing Web API's
If you’re looking for a dead simple web-based tool for inspecting HTTP requests, look no further. HURL has an easy-to-use interface where you can submit URLs with headers and parameters then view both the requests and responses.
HURL also supports basic authentication and if you sign up for an account it will keep a running history of your requests. To view a complete demonstration of HURL, check out this video:

This looks like another great addition to my web development toolbox.
