Ian,

I believe the text below should accommodate the ad chain issue, at least from a technical perspective. Just one question:

Building on your text below, if “Site A” is an Ad Server, in a large number of cases the redirect will be simply done via JavaScript - i.e. “Site A” replies with a JavaScript code calling “Site B”.  Will the below be implementable from a browser perspective, considering that we might be seeing a large number of such redirects if we’re in the situation described above?

Thanks,

Ionel

This is meant to satisfy ACTION-194 and is a proposal for transitive third party exceptions. I'm not sure if it's necessary if we restrict things to "first-party/*" but if you want to list out "first-party/third-party" explicit/explicit exceptions, I believe it would be necessary for things like advertising networks to function.

"If a third party has been granted an exception on a page, then any resources fetched by that third party, including items such as images included by that third party, content dynamically fetched by that third party, or another third party that is redirected to (such as via an HTTP 302 status code) are considered to be covered by that exception. This applies transitively, meaning that if in a given context "Site A" is a third party and has an exception, if it redirects to "Site B" then "Site B" is covered by that exception, as would "Site C" if "Site B" either included content from or redirected to "Site C".
