Re: FW: [squid-users] proxy_auth help

Chris,

All that i know is that everything runs in order. So if it finds a allow
first it will allow and stop looking there. If it finds a deny first
then it will stop at that. This is the way my firewall works so i think
that this is how squid is working. Maybe someone else can correct me if
i'm wrong.
