Since there are obligations on first parties, and different obligations on third parties, I think that receiving the header just tells you how *you* need to behave, and doesn't give you any information about what header is being sent to other people.

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. > >
