As porneL stated, what you want is not to deactivate the cache, but to deactivate the history buffer. Different browsers have their own subtle ways to disable the history buffer.
In Chrome (v28.0.1500.95 m) we can do this only by Cache-Control: no-store
.
In FireFox (v23.0.1) any one of these will work:
Cache-Control: no-store
Cache-Control: no-cache
(https only)
Pragma: no-cache
