A mechanism for speculative prefetching of webpages and their subresources that are on a critical path of page loading *without* executing any JavaScript or creating a complex state of the web platform. This system is not purely “no state” because HTTP cache allows to create cookies and other state related to validating cache entries. It is important to note that the “NoState Prefetch” is not an API. Server side detection: https://bugs.chromium.org/p/chromium/issues/detail?id=796855
