[squid-users] Logging both x-forwarded_for and direct client address

[Paul]

Hi

I have several remote sites running a local copy of squid that in turn 
use a parent squid.

I want to improve the logging on the parent squid, at the moment each 
site has 1 real external IP address and many internal IP's e.g. 
192.168.1.x, in the parent squid access log I see just the 1 real IP 
address for all requests as expected.

Ive now configured the remote sites squid to add an X-Forward header and 
ive set

follow_x_forwarded_for allow all
acl_uses_indirect_client off
log_uses_indirect_client on

on the parent squid, the access log now shows the internal IP making the 
request i.e. 192.168.1.x

However all my sites have the same 192.168.1.x range, is there any way 
to make it log both the external IP AND the internal IP e.g. 
78.128.146.22,192.168.1.12 so I can narrow down what IP at each site is 
viewing?

I dont think there is such a config but if anyone has any ideas/pointers 
on how to achieve I would be grateful.

Thanks

Paul
