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

thx a lot,but do I understand correctly?

acl mydomain dstdomain .domain.net
always_direct allow mydomain
acl ASP urlpath_regex .asp
acl ASP urlpath_regex \.asp
acl ASP urlpath_regex asp$
acl ASP urlpath_regex \.asp\?.+
no_cache deny mydomain ASP

is the same like:

acl mydomain dstdomain .domain.net
always_direct allow mydomain
acl ASP urlpath_regex .asp
no_cache deny mydomain ASP
