[fw-mvc] Serving static content to Anonymous user

Hello,

I have a standard ZF (1.8.4) application setup, similar to the quickstart app.

The idea is to:
- Serve cached "page" for Anonymous users and
- Bybass the cache for signed in users.

Ideally where should I place the check for registered user, and start the page cache?

Will it help if I provided my index.php and bootstap.php code?

cheers,
