I also found this posting from mail list: http://www1.ro.squid-cache.org/mail-archive/squid-dev/201004/0015.html http://www1.ro.squid-cache.org/mail-archive/squid-dev/201004/0015.html It looks like the guy there is having the same request as I have. What do you think about this Amos? Actually I wonder about this directive: qos_flows parent-hit=0x30 It looks like the Squid will mark the traffic if it is a HIT from parent cache peer, BUT: How is the parent HIT determined? Based on what? X-Cache Header or ICP protol or...?
