I have a haproxy configuration run in http mode. I pass requests to backend java servers. I use forwardfor option to get client ip in backend server. I want to get source port in backend server but there isn't any option about this in haproxy conf.
From maillist, i learnt, proxy protocol can be used for this. But i couldn't find any document or how-to about implementation of proxy protocol.
Can i pass source port information to backend server only changing load balancer configuration?
