I’m using haproxy infront of some NGINX instances, but only for some
instances which are being loadbalanced by haproxy, there are other
instances which go straight through.
I realise I need to change the logging format in NGINX to enable
X-Forwarded-For in the access logs.
The question is whether I can conditionally format the logs, i.e. use
“X-Forwarded-For” if it exists, otherwise use the normal NGINX logging
I’ve had a quick peek at the manual, I’m thinking maybe this can be done
with a map of some sort ? Maybe there’s a better way ? To be honest
I’ve no idea where to start, and I’ve never used maps before anyway !
