Should it be possible to terminate SSL for wss (secure websockets) at a layer 4 load balancer?
Seems to me that wss (and ws) in general would require TCP routing since an HTTP reverse proxy wouldn't be able to make sense of the packets; and, SSL termination would require layer 7 routing since the session is really maintained above layer 4. I feel somewhat confident about the first statement, and much less so about the second.
Bonus question. If it is possible, in general, to achieve wss routing and ssl termination in a single load balancer, can it be done specifically with HAProxy? Nginx? Other?
