Hi, I notice that recent HAProxy has support for being a TCP Fast Open Server, and I have a requirement to also add support for HAProxy to be a TCP Fast Open Client for those upstream servers that support it.
This is for a scenario where there is a satellite link between HAProxy and the servers, so every Round Trip we can remove helps a lot. Before I dive in, is anybody already working on this, or has anybody already investigated whether this is feasible? Best Regards David
