No Cache for logged in users

Hi Ahmed,
thank you for your work and great plugin. It is highly appreciated.
One question: I might be wrong, but it seems, that when I am logged in as an Admin, the page is cached including the Admin Bar. Basically when I log out, I still see the bar like I would when I am logged in = cached.
Is there a way to cache only for visitors but not logged in users?
Thank you,
Matt
