Possible to cache two versions of a page?

Great question, as this is something that will be crucial for me in the near future...

The User Guide states caching can be enabled on a per-page basis, but I'm not sure exactly how a "page" is defined in CI lingo.

Check out the application flow chart (here: http://ellislab.com/codeigniter/user-gui...pflow.html), and in step 3 we see the routing determines whether or not a cache exists. I'm going to have to get a bit more in the weeds with this to see how it works, because it almost looks like it would be per-URI without regard to security. (I can't imagine that's accurate, but that's how it looks.)
