Once the request has completed, a SERVICE_STATUS event will be generated indicating the result of the request. The correlationId will be returned in generated message. It can also be used to cancel this request before it completes by calling the Cancel operation. Note the supplied correlationId MUST BE unique from any "active" correlation supplied to this session via any operation(e.g., "subscribe", "sendRequest"). A correlation id is active if the request for which it was supplied is still pending, or if it refers to a subscription request that has not been terminated either explicitly or by an unsolicited termination.
