[squid-users] client identifier in squid logs

Hello,

I have an interception proxy configuration using WCCP and a Cisco
router. PAT/NAT happens on a device before the proxy, so my logs show
only the public IPs.

*Inet*
  |
Router---Proxy
  |
Firewall (PAT/NAT)
  |
*internal private network*

I checked the HTTP header, but can't find any host identifier info
there. Without changing the placement of the proxy or moving away from
the interception configuration, am I able to get the internal IP of the
clients added to my logs?

I know this is a far stretch, but I'm hopeful someone else is in this
predicament and has come up with a solution/workaround.
