Squid cannot cache HTTP responses without bumping HTTPS traffic. This is
a protocol-level limitation, not a bug.

There are known delay pools bugs for not-bumped (i.e. tunneled or
CONNECT) traffic. IIRC, the pools may work for some tunnels, but the
imposed limits may vary significantly from the configured values.

Do the unwanted logged records match zabbix_proxy?

* If yes, I am out of ideas. If you share a debugging log dedicated to
the incorrectly logged transaction[1], I may be able to figure it out.

* If not, then perhaps I misunderstood what your zabbix_proxy ACL means
to you. You may need a different ACL.
