HeartBeat explanation

[pmarques]

Hi,

Can you clarify the workflow of heartbeat?
I'm implementing the Socket.IO protocol, but reading this spec and "sniff" some socket.IO packages of a JS implementation make me a litle confused.
This spec tells that "it's up to the client to decide the padding", but has far as I can see this is done by the server, the client only reply to the Server HeartBeats (instantly). In other words, i didn't realize if the initiative to send the heartbeat comes from server or the client.
So, If is the server who has the initiative, maybe this spec is a bit unclear?

Regardes,
Patrick

In general Im finding the documentation surrounding socket.io very lacking... it does work pretty well but learning about it is turning into a quest in its own...

from my experience,heartbeat initiative come from sever,the client may modify this number according itself case!
