I don't think that's the same question.
"How can I configure Squid to try IPv4 if IPv6 fails" deal with a network-level
failure to connect to something.
I think the OP is looking for a way to tell Squid "for this destination
hostname, don't even try to connect over IPv6, because if you do, we'll get
rejected (not at the network level, but some application-level) so we need you
(Squid) to connect using IPv4 only (for this destination)".
