Title: Re: [ebxml-msg] Groups - ebXML Messaging TC weekly call added
Some comment below, also see the proposed update in
separate message.
L943-945: This option requires an intermediary to
execute the routing function for a message as soon as it is received on the
transport level, even before it is acknowledged [on the transport level].
Otherwise the error cannot be reported back on http response.
I would assume that an Intermediary
must always support the default option, so Intermediaries are not allowed to
just store and acknowledge the message on the transport level and than process
it further. Do we want such a requirement? I would propose to rename this option
to something like “Synchronous reporting”
The idea is indeed that an intermediary should (default
case) check whether it is actually able to route a message, by checking if the
message matches a pattern in the routing table. This is an inexpensive
operation, different and separate from the more expensive operation of
actually performing the action associated with the pattern (e.g. push the
message forward to next hop, possibly SSL handshakes etc.). Especially
with SME endpoints connecting to an edge intermediary, getting this failure
instantly on the HTTP back-channel seems to me by far the preferred
option. They may not connect the intermediary for hours or days after
pushing out a message and would have no signal that anything went wrong, so
instant feedback is required. See the proposed
update.
