Service Worker Cache Simulator
Simulate sequential GET events with five strategies; cache hits cost 0 ms, only 2xx responses are stored, HTTP errors resolve from network, and only transport failures trigger network-first fallback. Background revalidation completes before the next event. Same synthetic base origin, no expiration/HTTP cache/Vary/opaque responses. No service worker is installed or network/storage accessed. Up to 200 requests.
