CMsgMsmqHdr - this header information is prepended with users header info
|
|
found in AuxData. This is primarily used by ack receivers so they can
|
|
can obtain the target queue and sent time of the message. There are a
|
|
couple of reasons why we store this information and not rely on msmq msg
|
|
props : 1 ) msmq cannot ensure that a returned message has not been
|
|
tampered with and 2 ) the target queue should be a logical name that a
|
|
user will understand, and not some format name that msmq will substitute
|
|
such as with public queues pathnames.
