Can CHIPS support CSV in partition keys for RWS? #179

Open anushshukla opened 11 months ago

anushshukla commented 11 months ago

Let's take an actual example of our live environment to explain the problem statement and solution.

https://vwo.com and https://wingify.com are part of the same RWS while https://dev.visualwebsiteoptimizer.com is a third-party script loaded on these 2 websites that can create third-party cookies as CHIPS.

We would like to have the ability to add comma-separated values as the partition keys if these domains are part of RWS so that these CHIPS-based cookies can be shared across different domains if they're part of the same RWS.

We look forward to your response!

Hi @anushshukla,

Thanks for filing! It looks like one of your colleagues brought this up to us already in https://github.com/WICG/first-party-sets/issues/94, but this is a tricky problem that we haven't found a great solution for yet.
