Same URL /zh/tools/image-format-converter after refresh confirms the hot path: HIT, age=108 (~1.8 minutes since fill), Worker 333ms→8ms, Edge≈9ms, origin=0. Cache fill is healthy. On HIT, max-age moves from Worker’s 0 to 14400—same as home HIT—pointing to Cloudflare Browser Cache TTL (4h) rewriting at the edge; on miss the designed max-age=0 still appears. Conclusion: R2+Cache path is healthy; to force browsers to revalidate every time, set Dashboard Browser Cache TTL to Respect Existing Headers.
