Body: <p>I want my HTTP traffic on port 3701 and my WS (websocket) traffic on 3702. For a moment I thought that using 2 target groups was the answer, but there doesn't seem to be a way to differentiate between WS and HTTPS traffic using an ALB.</p>
  
  <p>So perhaps using a NLB (network lb) will allow me to differentiate between the two? How can I have one load balancer forward traffic to 2 different ports?</p>
