"In this context, an error is any situation which would result in a 500, 502, 503 or 504 HTTP response status code being returned." It seems wrong to limit this to these four status codes. Why not have the server indicate that stale responses are okay when it returns the error response? In other words, instead of returning stale-if-error=XXX on a successful response, it would return it in the 5xx responses. Alternatively, allow the stale-if-error subfield to list the status codes for which a stale response could be returned. Also, I think that the specification needs to explicitly mention that a warning should be added when a cache returns a stale response due to a back-end error. Regards, Brian
