The only way you will get most portal type sites (i.e. most web
accesses) to work in offline mode is by very aggressive
caching. Such caching has been demonstrated to make other
users' web email become readable instead of ones own, unless
one is very careful to work out which pages really can be
safely cached in spite of their apparent non-cacheable status.
You will also have to do ad-blocking, as many adverts are now
dynamic.

The only way of force validating with squid is to scan the logs
(or process swap.state) and issue conditional GETs for
everything. Such activity will be against the conditions of
use of some popular sites, and at least one squid user has
recently added throttling to stop this sort of activity
by his customers. Forceably caching nominally uncacheable data
is likely to be outside the terms of use as well, if it results
in adverts not being updated as frequently. IMDB consider
ad blocking a violation of their conditions of use.
If you do revalidate automatically, you will defeat the squid
expiry mechanisms, as the pages will appear to have been
accessed recently.
