Resources should have an explicit caching policy specifying if, by whom, and for how long they can be cached, along with efficient revalidation when the policy expires. Use `Cache-Control` to define caching behavior and `ETag` for revalidation. A minimum cache time of one week is recommended, with up to one year for static assets. Use URL fingerprinting for precise control over resource invalidation.\n"],null,[]]
