Type: Settings Directory
Counters of the cached objects the proxy revalidated with the server before it answered the client. To revalidate an object, the proxy sends a conditional request with If-Modified-Since or If-None-Match. Each counter counts one reason. For an overview of caching, see Web Proxy.
