HTTP is a stateless protocol. There is no session concept at the level 
Squid operates. That is a purely web-application-layer thing in the browser.

A browser being shutdown and re-opened is indistinguishable to Squid 
from a browser simply opening a new TCP connection. Which happens 
routinely without the browser being shutdown anyway, since browsers use 
8+ (up to several hundred) of TCP connections in parallel.

So while there is a "first" authentication (as in "first ever" or "first 
since N minutes ago"), there is no "last".

To get the details you ask for, look at what the helper can report in 
its debug output, or adding a wrapper script around it that does the 
logging you want.

BUT, it should be clear from the info I gave above that what you seek is 
simply not going to be visible in any information Squid or its helper 
can log.
  What the access.log entry is saying is just "this request had 
credentials for X, they were checked and valid when this transaction 
started.". Nothing about any session thing.
