I see. A different approach would be to define an am-I-still-here IQ send to the bare MUC address: <iq type='get' to='r...@muc.example.org' …> <am-i-still-here xmlns='…'/> </iq> upon which the MUC either returns a result response containing the nickname if you are still joined <iq to='u...@example.com' type='result'…> <joined xmlns='…' nickname='.'/> </iq> or a result response indicating that you are not longer joined <iq to='u...@example.com' type='result'…> <not-joined xmlns='…'/> </iq> or an error response, for example if the IQ is unknown.. Advantages I see here is - The MUC does not intercept IQs - Hence it is not so easy to produce an implementation which would leak MUC nicknames - We sidestep the "IQ to MUC participant" problematic - We do not add additional semantic to xep199 pings I think I would slightly favour this approach. - Florian _______________________________________________ Standards mailing list Info: https://mail.jabber.org/mailman/listinfo/standards Unsubscribe: standards-unsubscr...@xmpp.org _______________________________________________
