Comment (by Jan Urban):

 This ticket is about avoiding the possible misunderstanding of how `no-
 cache` works in browser.
 This ticket should not change the functionality of `no-cache` header and
 the end result of the `patch_cache_control` and how the header is
 interpreted. (As far as I know)

 Needs more verification and discussion, if we should lead the hand of
 others.
 As mentioned as it could be security issue as well if the value is
 interpreted wrongly by the others.

 I do not know how exactly the `no-cache` works and what are the
 conventions for it and best practice, but this sounded like it make it
 more explicit.
