I have a problem with HAProxy server. I want to forward in header a client IP. I almost done it, but there is interesting case and I can't figure it out. I need to write client IP in 2 places in header, in X-CLIENT-IP and X-FORWARDED-FOR tag's.
The problem is: When I use
option http-server-close option forwardfor
On target server I see in header X-FORWARDED-FOR=xxx.xxx.xxx.xxx(client ip) but there is no x-client-ip header.
When I use:
option forwardfor header X-Client-IP option http-server-close
On target server I see header X-CLIENT-IP=xxx.xxx.xxx(client IP) but X-FORWARDED-FOR=xxx.xxx.xxx.xxx(HAProxy ip)
I need to see on target header where X-CLIENT-IP and X-FORWARDED-FOR has value of client IP.
I try to mix configurations like
option forwardfor option forwardfor header X-Client-IP option http-server-close
No efect. I can not also install any modules. The target is IIS.
Any ideas? :(
