The squid.conf docs for udp_incoming_address specify that its ICP-only related. However the Config.Addrs.udp_incoming is used by ICP, HTCP, and DNS.
Similarly, docs for udp_outgoing_address specify that its ICP-only related. However the Config.Addrs.udp_outgoing is used by ICP, HTCP, syslog, and DNS. This is from the 2.6 docs, I haven't checked 3.0, but its likely the same. Anyone have suggestions on what should be said? Amos
