Question

I am using the fantastic Oauth2 server library from Alex Bilbie. It works perfectly fine but I am not sure how to use the Resource Server. What is that?

Thankful for all input!

Answer 1

From the specs draft-25 section 1.1:

resource server: The server hosting the protected resources, capable of accepting and responding to protected resource requests using access tokens.

So, a resource server, can be any application (usually an API) with functions that requires OAuth authenticated access.
