 The `CF-Cache-Status` header output indicates whether a resource is cached or not. To investigate cache responses returned by this header, use services like [Redbot](https://redbot.org/), [webpagetest.org](http://www.webpagetest.org/), or a visual tool like [Chrome's Dr. Flare plugin](https://community.cloudflare.com/t/community-tip-dr-flare-debug-tool-for-cloudflare-chrome-extension/110166).
