If a server always responds with 204 after a successful HTTP DELETE, when is it appropriate to require clients to send an Accept header? It seems like the correct behavior would be to never require an Accept header. The reason I ask is that when developing a RESTful Rails application, if the Accept header is unset, Rails defaults to HT...
