In HTTP you have many requests associated with a session id. With session
replication, each new request could go to a different server and still
access the same HTTP session attributes.

In WebSocket on the other hand there is a single connection the server and
if you lose it, you have to reconnect, which is probably what pressing F5
does for you. Unless I'm missing something, you have to detect when the
WebSocket connection is closed on client side and reconnect.
