:Squid (or Apache) will work fine, but under very limited circumstances:
:
:o The cached object is a 'final' document, rather than a 'part' (eg. a banner
:or toolbar)

the cacheable object is a final document, but it could be
cacheable if you have some least common denominator of the 'parts'
(the assembled document would be as young as the youngest part). 

:o Your cache rules are *very* simple

you would have to revalidate every object.

:o You don't need authentication or side effects of the URL lookup

there are cases where even authenticated sessions can produce
cacheable objects, for instance static images. 

:o You're willing to explicitly kill the cache, or just wait, when you make
:changes

no, you just would have to tell the cache to look if the requested
document is younger than the one cached.
