Information about a cache entry to be removed is contained in a CacheEntryUpdateArguments object. A CacheEntryUpdateArguments object is passed to the CacheEntryUpdateCallback delegate. The method that implements the CacheEntryUpdateCallback delegate can pass an updated cache entry value back to the cache implementation. The updated cache entry replaces the cache item that is about to be removed.
