It is close. That would stop the Location header getting to the client
Browser. But the 302 status still will, and given that the Browser back
button functionality is not working like it used to (a browser bug?),
the full result may still not be worth it.

I would use the http_reply_access to deny instead. That way the client
gets a 403 status from Squid and definitely none of the upstream's redirect.

If you want to be more fancy than 403, the current Squid can attach a
deny_info to the ACL to make the denial have 451 status with custom
template page explaining the block to any user that sees it.
 (Which is what your upstream should have been doing.)
