When using the REST interface for Last.fm web service, are the "Etag" and/or "Last-Modified" HTTP headers provided in the responses?
E.g. let's say I plan on using the track.getTags API method, is either "Etag" / "Last-Modified" HTTP header sent along with the response?
(NOTE: I have asked the same question on Last.fm's "discussion board" but it seems there is low activity there... I am probing SO's vast collective knowledge here)
