Cache-Control and ETag headers missing in 304 responses
200 responses generated by Cloudflare Pages include a
Cache-Control: public, max-age=0, must-revalidate and ETag headers. But those headers are missing in 304 responses.
RFC 9110 mentions the server MUST generate those headers [1]:
The server generating a 304 response MUST generate any of the following header fields that would have been sent in a 200 (OK) response to the same request: - Content-Location, Date, ETag, and Vary - Cache-Control and ExpiresIs it an oversight or is it on purpose?
