Re: Revised Response Header

Here are some answers that a user-agent or intermediary probably should be able to get from the response header:

* is this a non-trackable request by its nature (i.e. something that is not, or could never be, tracked, such as a cacheable object)?
* do you think you are operating under 1st party or 3rd party rules?
* what DNT status do you believe you are operating under?
 -- DNT:1
 -- DNT:1 with an out-of-band opt-in
 -- DNT:0
* are you, or might you be, tracking this request, because of an
 -- opt-in of some kind?
 -- exception of some kind?
 (or are you 'completely respecting my DNT:1 without exception?)
