I've been reading a lot of these articles and would like to think that I've implemented a RESTful API. I use GET for the get_all, get_one methods; PUT for create and PUT for replace/modify (as in replacing a field, not appending to it), HEAD for checking if certain resources exist, and DELETE for the obvious.

The framework I'm using assigns any visit a new session, but it's unused in the sense that the REST interaction doesn't require the session and also doesn't use it - authentication is handled using a the "Authorization: basic" header.
