Iframe and CHIPS storage access #49

Closed amaliev closed 1 year ago

amaliev commented 1 year ago

The current spec should require no changes for iframe/subresource access - these are already tracked as stateful accesses under the top-level site. If we assume partitioned 3P cookies and 3P storage, all accesses by a 3P subresource may be used as a DIPS workaround (via a client-side redirect) and should be tracked accordingly.

LGTM. @jyasskin are you ok with this caveat in a note or do we need to do something different?
