RE: Reliable messaging

That is often an option, but not always. You can also build in mechanisms 
that provide
for the receiver to determine if a given message is a duplicate 
(messageId) resulting
from a resend. The receiver can choose whether to process or ignore it 
based on
whether it can or cannot be safely processed.
