Hmm... I indeed got that wrong. According to the draft spec secion 8.3, no header present is an OPT-IN. However, since we always send "DNT:1" or OPT-OUT by default, this should not be an issue. A user can then uncheck the box to OPT-IN (DNT:0) if they so desire. And since not sending the header is the same as "DNT:0", then there is no reason why we should not explicitly include it in the header sent to the server. Regards, Dawit A.
