I saw this feature, but I think there is limitation preventing me to use it, tell me if I'm wrong ;) - I cannot use this to make a call each time a message is published on a pubsub websocket - I cannot modify the message sent by the user (to add user information for example)

Also, what do you mean by multiplexing websockets ?

That's correct, that feature is for authentication only. I may add a feature to replace the message with the back end response.

By multiplexing I mean that a single websocket (or any other) subscriber can subscribe to multiple channels.
