well, that's a theoretic thing, but..
scenario:
I have a page, and give only logged-in (or a specific group of) users access to it.
I test my website (same pc) and see the locked page if I'm logged in the cms as admin.
When I log out from the cms an refresh the website the locked page disappearces...
hope you got it ;) I'm out of practise with english...
