**Is your enhancement request related to a problem? Please describe.** If a client need to publish to 2 different topics, it will take 2 tcp connections between the client and the broker. 3 topics, 3 tcp connections etc... if ssl is enabled this is more costly. **Describe the solution you'd like** It would be very handy to be able to specify all the url info in the websocket message instead. There are multiple websocket apis that do that, like [wamp](https://wamp-proto.org/), [wamp publish doc](https://wamp-proto.org/_static/gen/wamp_latest.html#publish-0) or [cobra](https://machinezone.github.io/cobra/api/). I'm trying to look at the [pusher api](https://pusher.com/docs/channels/library_auth_reference/pusher-websockets-protocol) but cannot find the details, however it looks possible to make multiple subscriptions with a single client. For publishing, instead of doing this: url: */ws/v2/producer/persistent/:tenant/:namespace/:topic?param1=too¶m2=bar ``` { "payload": "SGVsbG8gV29ybGQ=", "properties": {"key1": "value1", "key2": "value2"}, "context": "1" } ``` Do this: url: */ws/v2/producer/persistent/:tenant/:namespace/:topic* ``` { "payload": "SGVsbG8gV29ybGQ=", "properties": {"key1": "value1", "key2": "value2"}, "context": "1", ---------- Extra args --------- "action": "producer", "persistence": true, "tenant": "a tenant", "namespace": "a namespace", "topic": "a topic" "params": { "param1": "foo", "param2": "bar" } } ``` **Describe alternatives you've considered** Writing a proxy broker that does this ? **Additional context** If a client needs to publish to 10 topics, or 50, it will need to create 10, 50 tcp connections to the broker which is not scalable.
