[99s-extend] Heartbeat?

[Lee Sylvester]

Hey guys,

So, my bullet websockets are going great.  However, I have a question.  At present, if I don't send any data to or from my websockets for a while, the connection closes after about 10 - 20 seconds.  Therefore, should I send a heartbeat to the client from Erlang to keep this open?  The websockets are for user to user messaging, so it's possible that large periods of inactivity could occur.

Thanks,
Lee
