Is it possible to notify application when item is removed from cache ?

HttpRuntime.Cache.Insert(

            "CacheItem1", //insert cache item

            "",

            null,

            Cache.NoAbsoluteExpiration,

            new TimeSpan(0, 0, 15),

            CacheItemPriority.Default,

            new CacheItemRemovedCallback(RemovalMethod)); //define method which needs to be called when item is removed from cache

private static string RemovedAt = string.Empty;

    public static void RemovalMethod(String key, object value, //method is declared static so that it can be available when cache item is deleted

        CacheItemRemovedReason removedReason)

    {

       RemovedAt = "Cache Item Removed at:  " + DateTime.Now.ToString(); //Shows the time when cache item was removed

     }
