Define keepalive protocol The keepalive program has two procedures: PING, and PONG. Both are used only in asynchronous messages and the sender doesn't wait for any reply. However, the party which receives PING messages is supposed to react by sending PONG message the other party, but no explicit binding between PING and PONG messages is made. For backward compatibility neither server nor client are allowed to send keepalive messages before checking that remote party supports them. 2011-09-22 10:51:55 +00:00			`const KEEPALIVE_PROGRAM = 0x6b656570;`
