Works very well -- OAuth too!

Very well done app. If youre looking to assemble RESTful requests and want to see a breakdown of the raw Request Header, see the raw Reponse Header and the Response Body (pretty-printing is an option), then this app is for you. You can launch multiple requests sets, and even save them. Great app and easily worth a couple bucks.
