I bet you are right! If it is bug 4906 "src ACL mismatches when access
logging TCP probes" then IP-based ACLs will not work in the
transaction-end-before-headers context. I hope the "Test 3" approach
quoted below can be used as a temporary workaround in supported Squid
versions.

FWIW, Factory has a (large) project fixing bug 4906 and many similar
bugs. It is going through painful internal review cycles, but I hope we
will request an official review soon.


Cheers,

Alex.
