Sending a response to a client

After processing a request, the server uses IXCSEND SENDTO=ORIGINATOR to send a response message back to the client. When using IXCSEND to send a message, you must provide the message content, identify the sender, specify timeout values, and identify the entity responsible for invoking IXCRECV to receive the results. When sending a response to a client request, you also:

Identify the target request. See Identify the target request.
Optionally, specify additional response information. See Specify additional response information

If a server sends more than one response to a request, at most, one of the responses is presented to the client. The remaining responses are either rejected at the time of the send or discarded (by either the sending system or the target system). The XCF client/server interface does not define which of the responses is to be delivered to the client.

If the client request exceeds ts RESPTIME timeout value or is otherwise completed or cancelled before the results arrive on the client system, XCF discards the server response message. In some cases, XCF rejects the server IXCSEND request outright if the response is sent after the client RESPTIME timeout value has expired.
