Vary based on whatever is identifying the user as logged in (Cookie I
guess).

But this will pretty much invalidate the whole cache in most cases.

Better solution: Redesign the site to not differentiate between logged
in or anonymous users for the actual content, and have the CMS add
logged in functionality on the client side by using DOM instead. This
way only one javascrip needs to be dependent on if the user is anonymous
or logged in, not the whole site.

Another solution but not as transparent to the users: Use slightly
different URLs for logged in or anonymous access. I.e. https for
authenticated users and http for anonymous access.
