3.2.4.2.1.2 KeepAlive Message

This message is sent by the client on the secondary HTTP connection to prevent the connection from timing out due to idleness. The client MUST only send KeepAlive messages while the primary connection is alive; when the operation finishes, both connections are closed. The ResourceURI and Action elements for the KeepAlive message MUST be as shown here.
