In reading a separate thread, I realized that there is a potential issue here over DNT:0. A little while back we discussed whether the UA should send a DNT header to the first party. A number of us argued that it should, even if the first party is exempt: because the first party may care that its third parties are being asked not to track - it might ask for payment in consequence, for example. This argument relies on the assumption that DNT is a single 'big switch', either on or off, but the discussion around DNT:0 reveals that people think it may be OK for the UA to send DNT:1 to some sites, and DNT:0 to others. So what, then, does the first party get? DNT:1 if any third party is getting DNT:1, else DNT:0 if all are getting DNT:0? An average of the DNT values :-) DNT:0.7 ??! Am I, as a UA, allowed to mix non-DNT requests into the mix? David Singer Multimedia and Software Standards, Apple Inc.
