The bit that says to configure "cache deny" ? Simply prevents storage of the request/reply objects as they go through Squid. If I understand you correctly you want requests sent to a particular site not even to enter Squid yes? once they enter squid there is no bypassing, so it must be done at the firewall. For such sites I use a custom chain a bit like this to decide of the request is intercepted or not (all the lines ending in ACCEPT, are not intercepted): iptables -t nat -A squid -s 10.0.0.1 -j ACCEPT ... iptables -t nat -A squid -j DNAT --to-destination 10.0.0.1:81 You want something like: iptables -t nat -A squid -d ip-of-website-to-permit -j ACCEPT in your list of bypasses.
