Dynamically route to a backend or a server from a backend?

[planetinse]

Does anyone have http example of how to do this - and can give a example?

I have tried to route https (with termination) the same way this is is done (thats working with HA and pfSense)

but i can't get it working with normal web traffic.

in my case iam trying to use the hostname with ssl_fc_sni (since i need to support websockets) and i have an internal DNS resolver that gives the internal IP for the server, i have tested with dig, that I do get the internal IP.
