Ping/pong with websocket extension?

[carrete]

Is it possible to periodically send pings with the websocket extension? Or is there some other way to prevent timeouts?

I went ahead and scheduled the backend to send pings every 10 seconds. I would have preferred to have done this in the browser. This would have eliminated the need to do any state management on the backend (no need to capture closed connections on the backend and unschedule pings). Couldn't figure it out in a reasonable time though
