HttpRuntime.Cache 缓存过期问题

Question

            
CacheItemRemovedCallback onRemove = null; //CacheItemRemovedCallback对象
            onRemove = new CacheItemRemovedCallback(ItemRemovedFromCache);
            HttpRuntime.Cache.Insert(
                CacheName,
                Count,
                null,
               DateTime.Now.AddSeconds(10),
               TimeSpan.Zero,
              System.Web.Caching.CacheItemPriority.High,
                onRemove
                );
缓存设置这样是 DateTime.Now.AddSeconds(10) 10 秒过期 没错 吧 ，可是程序运行就老是没过期
调试查看 absoluteExpiration 时间是 9999/12/31 23:59:59  就永远不会过期啊 为什么呢 各位大侠
们 Help！！！

我也是，HttpRuntimeCache 就不过期，可是改成  HttpContext.Current.Cache 会准时过期
