Hi! My view on ISSUE-106: - During Brussels I discovered that cached objects can be used for tracking - Saying "cached resources imply 'no tracking' does not do the job Reasoning: If receiving a cached object (with http indication that it can be cached) without a DNT response, then the user cannot distinguish whether a site does not implement DNT (and may use this URL for tracking) or whether a site follows DNT and implies 'no tracking' Consequence: DNT response headers should be required for cached objects. Whatever language we decide to use for the header in general (should vs must; see ISSUE-121) should also apply for cached objects. Opinions? Regards, matthias
