OK, the TPE has the open issue of what to say about HTTP re-directs. Reading this email, the UA may be the wrong place to handle this, and that may be the wrong question. Thinking out loud here, perhaps a third-party receiving a DNT:0 'may' pass on the 'permission' to a server it re-directs to, if it wishes? That might be better than a general rule on re-directs (which I was having a hard time formulating, as re-directs are used for so many purposes). So, for example, a request GET http://ads.example.com/chocolate-ad DNT: 0 might get this HTTP response 302 Moved Temporarily Location: http://ads.foodies.com/deepdarkdangerous-chocs?dnt-status=0 and then, by the user-agent (presuming foodies.com is not on the user-exception list) GET http://ads.foodies.com/deepdarkdangerous-chocs?dnt-status=0 DNT: 1 might get the response 200 OK tk: 3;qrst (I could wish that this response answered the basic question, "am I being tracked?", but it doesn't, so…) and the well-known resource http://ads.foodies.com/.well-known/dnt/qrst indicates (among other things) "response": "tp" (indicating that tracking is occurring due to prior consent; though we might want a better letter-code than 'p' here to indicate that the consent was passed on) Would that serve the case?
