Not besides hacking the source (everything is possible by hacking the
source to various degrees).

Well, this is actually not entirely true. There are some support for
Cache-Control: public in 1.2beta which allows the site administrator to
allow caching of objects which is authenticated but not requiring
authentication.

In HTTP 1.1 it is actually possible to differentiade between 4 classes
of authenticated objects by using the Cache-Control header:

1. Public objects
2. Cacheable objects requiring authentication from each user
3. Cacheable objects requiring authentication on each use
4. Uncacheable objects

This aspect Cache-Control is more or less supported in 1.2beta
(currently it supports the public notion, more is to come). It is not
supported in 1.1.X as far as I know.
