Sorry, My description not enough.

In this environment, BIG-IP exist between end point PC and Squid.
BIG-IP do NAT, and add X-FORWARDED-FOR header.
BIG-IP include IP address of endpoint PC for X-FORWARDED-FOR header.

So, I use follow-x-forwarded-for feature, and get endpoint PC IP address .

This time, endpoint PC IP address is written into Squid access.log.

Maybe, source code is below,

AccessLogEntry.cc
----
#if FOLLOW_X_FORWARDED_FOR
    if (Config.onoff.log_uses_indirect_client && request)
        log_ip = request->indirect_client_addr;
    else
#endif
----

But, it is not assigned to environment variable of error page.

If environment variable of error page could support "indirect_client_addr",
I would really appreciate it.

I feel that way is difficult.
Because, solution of javascript only works JScript, or require STUN server.

I'm writing using Google translate.
I hope the feelings of my gratitude will reach you.
