Hello, It seems as if the always_direct directive is broken in squid3.
I have always_direct allow local-nets and local-nets acl local-nets allow dst 10.n.n.0/24 and if I try to hit 10.n.n.3, instead it tries to send to roundrobin_parent instead of direct. There are round-robin acls for the peers that would not prohibit the use of this destination network, like http://10.n.n.3 Sorry if this is not clear _J
