Figured it out. Cache-Control header is required.
js const headers = { 'Cache-Control': 'public, max-age=604800' }; const request = new Request('https://foobar.com/') const cacheResponse = new Response('bar',{ headers }) const cache = caches.default await cache.put(request, cacheResponse) const response = await cache.match(request);

fetch). In this case, the subrequest will be logged with a cache status, while the main request will be logged withnone/unknownstatus (the main request did not hit cache, since Workers sits in front of cache).- A Firewall rule was triggered to block a request. The response will come from the edge network before it hits cache. Since there is no cache status, Cloudflare will log as
none/unknown.- A redirect page rule caused the edge network to respond with a redirect to another asset/URL. This redirect response happens before the request reaches cache, so the cache status is
