This object reports or sets the status of a specific cache entry: settable to enabled(1), disabled(2), or empty(3, clears all cached data for that entry), while reads return values from disabled(2) through expired(5). Admins set this to empty(3) to force an immediate refresh of a specific cached data subtree without waiting for its timeout to elapse. Setting this to empty(3) on a specific cache entry immediately discards its cached data, forcing the next query to fetch fresh values from the underlying data source.
