Reply Events
Determining a Reply Event's Type
The content of a reply event can vary, depending on the design of the requestor and server applications. The request event's infoset defines the reply event that is expected.
A reply event may take one of the following forms:
*A null event that has no data.
*An acknowledgment that indicates the operation was successful.
*A single reply event containing application-defined data.
*A series of reply events containing application-defined data.
*An error reply.
If a series of reply events are returned, the appSeqn and appLastSeqn envelope fields may be accessed to determine the event's sequence position. See Envelope Fields for more information.
