RESTful Services You've heard of the two terms GET and POST.

But GET and POST aren't the only "HTTP verbs" - there's two more you should know about: PUT and DELETE.

Technically, POST should only be used for creating something - like creating a new Note in your awesome new web app, for example.

PUT is the verb for modifying something. And DELETE, you guessed it, is for deleting something.

Having these four verbs is a great way to separate an app up. It's logical. Unfortunately, web browsers don't actually support PUT or DELETE requests, which is why you've likely never heard of them before.
