Hello, while using squid 4.17 my ipv4/ipv6 ratio is about 56/44. When i use squid 5.3 my ipv4/ipv6 ratio is about 98/2. Both tests on the same host. Is it possible that the happy eyeball mechanism prefers ipv4 over ipv6 in th squid5 series ? -- Regards Dieter -- I do not get viruses because I do not use MS software.
