Is there any way through which I can control traffic from only few clients to connect directly to internet if the upstream parent proxies are down. For example, in an example configuration squid forwards traffic from client C1 and C2 to parent proxy P. HTTP traffic from client C1 and C2 <---> forwarding squid <---> P <---> cloud If parent P is down I want C1's traffic to be sent directly to the internet by squid, while for C2 the connection should be dropped by squid. "prefer_direct off" affects traffics from all the clients. Is there any way to use a combination of "prefer_direct off" and "never_direct allow all/ always_direct deny all" ? -- Regards, Nipun
