    🎉 [email protected] adds conditional revalidation for QUERY requests
    Express 5.3.0 code example. An app registers a QUERY handler on /reports that sets an ETag header of "12345" and sends a JSON array of results. A comment shows that a QUERY /reports request with If-None-Match: "12345" now responds 304 Not Modified, where it previously returned 200 with the full body.
