Please use the squid3 version from Lenny, its much more stable and less
buggy than the beta.

They both are. Pick the one that you like the look of most.

To meet your stated request either will do.

However I'd urge you to consider carefully WHY, you need to do this.
If the nature of the .asp pages is breaking your Squid, then its breaking
everyones elses' cache as well.

Squid will cache what it is allowed to, the asp web app should be giving
it correct Cache-Control and Expires headers. If these are missing squid
will estimate based on last-change.

For dynamic pages we currently recommend dropping the old default QUERY
acl, and using "refresh_pattern -i (/cgi-bin/\?) 0 0% 0" as the second to
last pattern. This makes squid discard all dynamic objects without working
expiry info immediately, while also letting those good sites that provide
expiry to work.
