It’s TCP layer 4 load balancing, so the HTTP hdr(host) won’t work.

At the moment I used the dst_port sample on the use_backend line. But that must be a concatenation of dst sample, “:” and dst_port sample. It seems like a basic thing to do, but I just can’t figure out how to do this. How do you access the frontend? If via ip:port instead of dns than I guess the ip:port combo will already be present in the hdr(host).
