What you want it to do then?

HTTP does not announce when an object changes. Instead it relies on

a) The web server to provide an indication when the object is expected
to change, done via the Expires and/or Cache-Control: max-age HTTP
headers.

b) If the web server doesn't give any freshness/expiry indication caches
guesses based on the modification age of the object.

Squid's guesses ('b') is tuned by the refresh_pattern directive in
squid.conf.
