Re: dial-up

The problem is that most larger sites uses dynamically generated HTML,
and isn't cacheable (only the images gets cached).

The directives you are looking for are

refresh_pattern
and
offline_mode

Be warned that fiddling around with refresh_pattern can very easily
cause Squid to cache private content like web-based email services and
other "sensitive" information unless the web-application is properly
designed to cope with caches.
