hi sqlcamel: In my Debian Squid2.7STABLE7's default config file, the 'nonhierarchical_direct' and 'prefer_direct' config options: By combining nonhierarchical_direct off and prefer_direct on you can set up Squid to use a parent as a backup path if going direct fails. But i could not get that work in my testing, the config is: cache_peer x.x.x.x parent 80 0 no-digest no-netdb-exchange no-query prefer_direct on nonhierarchical_direct off With no 'always_direct' or 'never_direct' Squid first use the parent not go directly. Anyone help?
