Squid works correctly already.
Set your web server and software to send the correct headers.

Therefore the above states that the object may not be stored after the
24th August.
Squid will *always* obey the strict Expires: header when its present.
If there is no Expires: header Squid will obey the max-age instead.
Using time since Last-Modified.
If there is no Expires: AND no max-age Squid will obey refresh_pattern
ages from a calculation using on Last-Modified.
