Use stale-while-revalidate and 304 Not modified

[paulnta]

Hello, Let’s say I have a resource that is fresh for a very short period, so it must be revalidated frequently: max-age=1, stale-while-revalidate=3600

During the revalidation, I’d like to avoid the origin to generate and send the full response if it has not changed. Is it possible to return a 304 Not Modified response to let Cloudflare know that the stale object can continue to be used?

Yes.

Your Origin needs to send valid Last Modified or ETag headers, so that there is something for Cloudflare to validate against.
