How can we configure this for different ports ( not only 443 / tls )

[Mandofskii]

I have 2 snis that send request to my sniproxy with port 1010
a.example.com:1010 tcp
b.example.com:1010 tcp

how can I configure openresty to proxy these domains with same port

because the port of two domains are same I can't define two different server with different port and I should determine the domain name and proxy to that .

I dont want to do load ballancing
some data should send to a subdomain and some to b subdomain.
