How can I limit the amount of incoming queries?
Greetings!

Is there any way to limit the amount of messages coming from connected users? 
I'd like to make a restriction for every user on 2-3 queries per second. 
I'm making an MMO browser game, and the users flooding the WebSocket server with queries might become a real problem (whether these are actual queries or fake ones, sent in order to cause lag). It would be nice if Ratchet could reject user requests if they are coming too frequently.

Thanks!
