I have posted some thoughts on www-tag [1] because of the relation with httpRedirections-57 [2].

Basically, recapitualtion of an idea that I trace back to Jonathan Borden in 2003 [3], which resurfaced for me earlier this year and which seems relevant to surface at this time. Some discussion and basically a question as to whether its an idea with merit that needs action (which I think amounts to some internet-drafts and message header registrations - ie. IETF process) or not.
