			we pass a pointer to the original message in the "Context" parameter of the "Send" function, and when
			"OnDataReplyReceived" is called, we retrieve this pointer by using "SavedContext()" in the Original msg we sent.
			Since MultiX automatically destroys messages it forwards to the application, we must call "Keep()" on
			the received message, to prevent it from being destroyed, in that case, when the reply is received, we need
			to destroy the original message ourselves.

			When we play the role of an acquirer gateway, usualy we get the request from the POS terminal, do validation required
			and maybe modify some data, and then forward the message to the issuer gateway, in our case, the forward will be to a process
