re-ordering your refresh_patterns so your local ones will work will help
things a little. Otherwise as others have said this is fine.

The default . and cgi-bin refresh_patterns supplied by Squid MUST be last
on the list. Also note the updated syntax of the cgi pattern to prevent
early discarding of mis-matched URL:

refresh_pattern -i (/cgi-bin/|\?) 0 0% 0

> refresh_pattern . 0 40% 40320
