Our app servers are sending the Vary on the Accept-Encoding when compression is requested. If compression is not requested they do not perform the Vary. Does that mean we should find a way to send a Vary: Accept-Encoding: null,gzip,deflate or something? Is there a 'no compression' accept-encoding header?
