Squid works correctly already.

Set your web server and software to send the correct headers.

... 17th August + 1 week = 24th August.

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.
