<br>
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.<br>
<br>
I realise I need to change the logging format in NGINX to enable X-Forwarded-For in the access logs.<br>
<br>
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 format.<br>
<br>
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 !<br>
