Related notes:

WONTFIX. A server must respond to any GET request for tracking status,
at any time, and not necessarily corresponding to any specific request
on a designated resource. In other words, they are independent resources
and the user agent decides when (or if ever) it makes a request for the
tracking status.

Real-time bidding does not have an impact here. Each time a user agent
is presented with a resource to fetch (i.e., perform a GET on some URI)
it makes a decision whether to request the tracking status or not.
There is no requirement for the UA to do so: the protocol is satisfied by
the DNT preference expressed, so the tracking status resource exists for
the sole purpose of verifying (or finding more information about) compliance.

If the UA chooses not to verify compliance, then no additional requests
will be sent. If the UA chooses to verify compliance prior to making a
request to a new site, then it will do so after it has been provided the
URI by the real-time bidding algorithm (the URI of the bid winner).
Assuming the bid winner claims to conform to TPE, the tracking status
the UA receives must remain valid for at least 24 hours (or longer if
cache control specifies a specific TTL). Note that the tracking status
of the bid winner is separate from the tracking status of the bidding
process if they are separate HTTP requests; if the market acts as a
gateway and provides the bid winning response itself, then the market
is responsible for the tracking status of itself and all downstream
recipients (those it shared the request data with).

Our expectation is that only a very small number of user agents will
actively verify compliance and will only do so once per site. Some
UAs might rely on others to verify compliance, or limit such checks
to sites that have a bad reputation.

Suggestion from Shane: http://lists.w3.org/Archives/Public/public-tracking/2014Oct/0064.html

Nick Doty, 15 Oct 2014, 16:04:46

Shane raise the issue of exchanges that forward the request data to a set of parties and then want to respond with the tracking status of the selected party (the winning bidder). I have tried to address this in r1.274.
