Your proxy log will tell for sure.

Again your proxy log.

Your proxy log will tell you if the page was fetched from cache or from
the Internet, or if it was denied by Squid.

Use refresh pattern settings to deny Squid giving the user a news page
which is older than 4 hours.

Three things I can imagine did happen provided that your Squid
configuration did function properly:

a) Your boss had the page cached locally and his browser did not even
bother to try to verify that the page was fresh.

b) The browser did verify that the page was fresh, but selected to view
the previously cached version when access was denied.

c) Your boss did bypass your Squid proxy or access rules somehow. Maybe
you have an exception giving your boss access all time, or he isn't
using the proxy.

Squids http_access checks is performed on every request.

miss_access checks is only performed when Squid needs to contact another
server.
