I know many sites dont want logged in user's pages cached.
However, there are many sites, including several of my own that display varied content to different user levels (vis S2Member of course!!) and everything else being the same.
I think it would be extremely beneficial to be able to cache the logged in user pages by userlevel/role.
So, say we have 5 user levels, we can structure the cache folder to lookup by userlevel
What do you think?
