[squid-users] Log Setup

[creditu at eml.cc]

I have a 3.1 accelerator and have set the logs up to emulate _httpd_log.
 On the standard squid log I can see which backend server the request
was sent to:
 
1481343537.601      1 192.168.1.227 TCP_MISS/200 496 GET
https://192.168.1.102/ - ROUNDROBIN_PARENT/192.168.1.21 text/html

When I turn on httpd emulation I can't seem to come up with the
setting/option that will give me the IP of the backend the request was
sent to.  Is there a way to do this in 3.1?  I can get the
ROUNDROBIN_PARENT part, but not the IP.
