I have problem. I must make traffic load balancing between two internal machines.
There is requirement - traffic must be routed basing on client IP in such way that from one IP client connects always to the same backend server.
It is simple, but traffic from clients goes from external proxy service and the source IP is always the same. The originial source IP is only available in X-Forwarde-For HTTP header.
Is it possible to user XFF header in HAProxy?
Thanks in advance.
