Hi, I've got a two-apache reverse proxy setup, split over two hosts.
The problem I've got is that I'd like to put the user_id in the access logs so that our log analysis software can make use of it.
Setting apache->user correctly logs the user at the back-end however the IP addresses are wrong, being the internal address of the front-end proxy. Also requests dealt with purely at the front-end aren't logged.
Logging at the front-end means all requests are logged with the right IP address. Additional bonuses for me are that those servers are less loaded, and I'd be able to turn off logging at the back-end. However the user_id isn't available.
Is there any easy way to pass the user_id from the back-end in such a way the front-end could log it? Or is there another option?
