Hi Nick,

thanks for this proposal.

I believe that the current header spec covers this case by means of
the header response that says that a resource does not do any tracking
(beyond what might be permitted for third parties under DNT;1).

This corresponds to your text except that your text "except in
aggregated and anonymous form" is now replaced by a pointer to the
compliance spec.

Sites can then decide whether this resource is cache-able or not. Note
that cacheability and use-for-tracking are orthogonal since cached
resources can also be used for tracking (e.g., URL specific to user).

As a consequence, I suggest to keep these two values separate
  - DNT Response header
  - Cache controls

Other opinions?


Matthias
