Authorization control on Squid proxy server?

Question

Squid

Hello. Show how I can control the fact of authorization on the Squid proxy . In squid3\access.logI already see the direct activity of the user, but I would like to track the fact of successful authorization.

Answer 1

The task is not entirely clear; what is meant by "the fact of success".
At a glance, either make your own helper for authorization and issue it directly, or monitor traffic, etc.
More complex schemes, I think, should not be organized
