Related notes:

The effort by UAs to implement this feature seems prohibitive:
- All sites are required to implement "same-party"
- Browsers need to retrieve the well-known URI before sending request for all requests

Matthias Schunter, 11 Feb 2013, 22:33:43

It has already been established in prior discussion that it is impossible for a user agent to distinguish between a first party and a third party request. It would require understanding the reason a user chose to make an action, the extent and reasons why automated redirects are followed, and complete knowledge of DNS ownership for any subsequent embedded requests. This issue should be closed.

ISSUE-182: protocol for user agents to indicate whether a request with

DNT set is 1st party or 3rd party

http://www.w3.org/2011/tracking-protection/track/issues/182

Resolution:

- This seems technically impossible

- As a consequence, I suggest to close
