> And seems like the stale negative response is updated if proxy.config.http.cache.max_stale_age is short enough. Indeed, `is_stale_cache_response_returnable` refers `max_stale_age` but not `negative_revalidating_lifetime`. But if we have short `max_stale_age`, good 'positive' cache will be also unavailable shortly, that is not good. So regardless which value `is_stale_cache_response_returnable` refers, I believe that the proposal here is still meaningful to fix this issue, i.e. to provide a good 'positive' cache for long period but to make updating 'negative' cache possible and also to reduce requests to the 'negative response' backend. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
