And why would the pubsub service poke the publisher if not all the messages can be delivered? I think it would be the service's responsibility to retry the notifications. [O.] I didn't mean the service should poke the publisher for every delivery failure to the subscribers. Just to send a receipt back to the publisher that the item is published into the node. So the publishers has a guarantee the item was delivered to the node. From the node to the subscribers is a different story. > and receipt from subscribers to the server they got the > published item, thus the server could try to re-send the published > item in case no receipt is received in a finite defined time. Or this > kind of "receipting" is already speced in pub-sub and I missed it?... It's not in pubsub because it's in XEP-0184. A pubsub implementation could support message receipts so that it knows when items have been delivered, but I don't know of any pubsub services that do so now. [O.] ok, I got my answer. XEP-0184 is valid for pub-sub also. Thanks! Peter -- Peter Saint-Andre https://stpeter.im/ The information contained in this message may be confidential and legally protected under applicable law.
