Cache-control value 'immutable' indicates that a subresource does not change and so does not need to be revalidated on a normal reload. This can significantly speed up reloads and reduce network traffic. It is has been implemented in Firefox and is already used by Facebook. https://tools.ietf.org/html/draft-mcmanus-immutable-00 https://hacks.mozilla.org/2017/01/using-immutable-caching-to-speed-up-the-web/

We may want to implement Chrome-style reload behavior where non-expired subresources with explicit cache lifetime are never revalidated. This would make 'immutable' support unnecessary. Meanwhile, lets try this.
