+The client now starts polling the server again (to start receiving the `ping` packet), and includes the `sid` (sent in the handshake process) query parameter in all subsequent requests.
+
 At a given interval (the `pingInterval` value sent in the handshake) the server sends a `ping` packet and the client has a few seconds (the `pingTimeout` value) to send a `pong` packet back.
 
 If the server does not receive a `pong` packet back, then it SHOULD consider that the connection is closed.
