Re: [squid-users] deny cache of all .asp dynamic pages

thx a lot again !

it works now, but I have other question.

is this correct:

hierarchy_stoplist cgi-bin ? \.asp
acl QUERY urlpath_regex cgi-bin \? \.asp
cache deny QUERY

and can I leave this with the code above you suggested or I should comment out?
