Use the refresh pattern
refresh_pattern . 0 0% 0

This will cause Squid to validate any cached objects without any
explicit expiry time prior to sending them to the client.

When you are confident in how Squids refresh patterns work, begin adding
refresh_patterns to add more aggressive caching for content you want to
have more aggressively cached.

The min age should never be other than 0, unless you know what you are
doing.

In what way?

Sounds like you are running Squid as a "transparent" proxy. TCP
redirection of port 80 to a HTTP server is not supported by HTTP (or TCP
for that matters), and it is by far the magic tool which solves all
problems, even if some network equipment marketing guys seems to want
people to think so.
