Hello WebKit! We're working on an API to allow developers to declarative permit prefetch, and new prefetching which contemplates the need to avoid sending first-party cookies to other sites until the user navigates. Mostly in these two drafts: * https://wicg.github.io/nav-speculation/speculation-rules.html * https://wicg.github.io/nav-speculation/prefetch.html Managed as part of https://github.com/WICG/nav-speculation Thoughts and feedback are welcome. Thanks, Jeremy Roman Google Chrome team
