Michael, let me try a restart.
you need to use link-local addresses for the HTTP connection between a client and a printer. a link-local address has link-local scope. it is ambiguous outside of the given link (zone). see RFC4007. an application using link-local addresses must be bound to the interface in the chosen link-local zone. now the question becomes, what do you do with the embedded URIs containing link-local addresses? the referral clearly has no value outside of the given link-local zone. could you not infer the link-local zone of the referral from the transport session? given a link-local transport connection using a link-local zone, would it ever make sense that the referrals using link-locals would belong to a different zone? if not, then the client can just ensure to use the same zone for referrals that it does the transport it received the HTML over. cheers, Ole -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
