Hi, everybody!

I ask help to understand how HAProxy as LB (without Proxy Protocol enabled) rewrites IP-addresses in requests and responses.

I understand that when HAProxy accept request it changes source address on VIP and there is Proxy Protocol to save client’s IP.  
BUT I dont understand how it works with response from server to client.

I cant now to use HAProxy and check it by myself.

Thank you
