ISSUE-125: Way to test if a given user agent supports DNT

Way to test if a given user agent supports DNT

State:
CLOSED
Product:
Tracking Preference Expression (DNT)
Raised by:
Shane Wiley
Opened on:
2012-02-08
Description:
See action-84 for the history here. We are looking for a way for those receiving no DNT signal to know if that's because the user hasn't made a choice, or if it's because the user has a user agent that doesn't support DNT. We hope to address this via action-122.

Shane's explanation: A publisher has several options to manage “user granted exceptions”:


- 100% out of band – allows them to ignore the DNT:1 signal for users who grant the exception but the web browser will not be aware of this

- Mixed – request out of band exceptions from non-DNT users for some set of activities and only use browser user granted exceptions for those users that activate DNT

- 100% browser based – request all user granted exceptions through the browser regardless of the user’s DNT signal (this is the text Nick provided)
