RFC 2616 section 13.13:
(...) History mechanisms and caches are different. In particular history
mechanisms SHOULD NOT try to show a semantically transparent view of
the current state of a resource. Rather, a history mechanism is meant
to show exactly what the user saw at the time when the resource was
retrieved. (...)
All browsers but Opera ignore this. This means Opera _always_ uses cached pages when using back,
forward buttons. No matter what headers you send.
