Their only purpose as caches is to improve performance; there's no rule that they aren't allowed to contact the server to ensure that their response is
fresh enough.

RFC 2616 Sec. 13.1.1.

(1), which is "contact the server and ask" starts (see 13.3) "[w]hen a cache has a stale entry that it would like to use as a response to a client's request...." so it doesn't apply. (3) is for errors, so it doesn't apply. (2) does apply.

In general, contacting the server negates all performance benefits, especially for small files (like, say, Releases.gpg).
