RESTful API methods; HEAD & OPTIONS

Question

I\'m writing a RESTful API module for an application in PHP, and I\'m a bit mixed on the verbs HEAD and OPTIONS.

Answer 1

OPTIONS tells you things such as "What methods are allowed for this resource".

HEAD gets the HTTP header you would get if you made a GET request, but without the body. This lets the client determine caching information, what content-type would be returned, what status code would be returned. The availability is only a small part of it.
