Hi Charles, Why don't you simply respond with 200 and a cached representation? Telling the client to make another request for a different resource which is somehow less than this one is just going to make the overload worse while not satisfying the original request. A cached (or even canned) response will satisfy the request as if it were made at some point in the past, and will be recognized as such by the client because it is marked with age, cache-control, etc. As a practical matter, that is how all large CDN-based websites work. It only looks like the message is the most current representation of the resource because that's what the origin wants the client to believe. ....Roy
