If such correlation must be defined in terms of SOAP header blocks, I believe it should be defined by the SOAP protocol itself. This does not mean SOAP protocol should handle such correlation within it. According to the XMLP Abstract Model document, a SOAP user application may specify message-ids to correlate a request with a response. This requires SOAP protocol to somehow retain this information, either by transmitting it within a SOAP message (possibly in its header) or by providing such information to the transport layer through its service interface. > > Note that you need to specify how SOAP messages are carried in UDP's > PDUs. Also note that the SOAP processor did not change in both cases. Yes, I agree. I would also state that the SOAP user interface should not be affected by an underlying transport layer, since a user usually doesn't know about it.
