The discussion on REST/WS is still very much alive. There is an interesting thread of comments in Steve Vinoski‘s “WS references” post.

Note the references to “ProcessThis”. I wouldn’t have made the link between “ProcessMessage/This” with protocol handlers or interceptors in the same way that REST doesn’t link the transfer of state representation with HTTP GET. One is an architectural style concept while the other is an implementation technology which can be used to implement that concept. Very interesting discussion nevertheless.
