About this episode

Show DescriptionWe're joined by Thomas Steiner from Google to discuss his proposal for cross-origin storage, a new web API designed to bring back safe, cross-site resource sharing. We explore why the old shared-CDN caching model collapsed due to privacy and fingerprinting risks, and how this could solve those issues while avoiding those same pitfalls.
