2. The CE messages implies closing of all open transactions.
I would like to restrict this to happen only for the error
case. Only if the processor wants to close the connection but
does not expect to get any response for open transactions. If
a transaction should close without error, a TE message must
be sent. I am still fine that TE implies AME.
This should be already the case, essentially. Perhaps we need to
polish documentation. AME means "I am done sending my data". AME
does not imply disinterest in the other side data. TE means "I am
no longer interested in this transaction". TE implies disinterest
in other side data for the same transaction. TE does not imply
disinterest in other transactions on the same connection. CE means
"I am not longer interested in anything on this connection and am
going to close it". CE does not imply disinterest in other
Does this semantics meet your needs?
Did you change your mind or is there a misunderstanding? In another
mail your wrote that the AME messages in my example
http://www.martin-stecher.de/opes/sample1.html are obsolete. But if
the OPES processor sends TE before it receives all data from the
callout servr, it signals disinterest which is wrong. The callout
server often needs a signal to know that no DUM messages will show
up in this transaction and to return the last chunk of data.
That statement of mine regarding AME messages was inaccurate/wrong,
apparently. AME message is optional only if TE (or CE) message
follows. You are right that in the case of OPES processor, AME is
usually required to signal the end of original data (AME) without
signaling the loss of interest (TE). I think we are on the same page
now, aren't we?
