Rem ==================使用说明==============================================
Rem = 本类模块是动网先锋原创，作者：迷城浪子。如采用本类模块，请不要去掉这个说明。这段注释不会影响执行的速度。=
Rem = 作用：缓存和缓存管理类 =
Rem = 公有变量：Reloadtime 过期时间（单位为分钟）缺省值为14400, =
Rem = MaxCount 缓存对象的最大值，超过则自动删除使用次数少的对象。缺省值为300 =
Rem = CacheName 缓存组的总名称，缺省值为"Dvbbs",如果一个站点中有超过一个缓存组，则需要外部改变这个值。 =
Rem = 属性:Name 定义缓存对象名称，只写属性。 =
Rem = 属性:value 读取和写入缓存数据。 =
Rem = 函数：ObjIsEmpty()判断当前缓存是否过期。 =
Rem = 方法：DelCahe(MyCaheName)手工删除一个缓存对象，参数是缓存对象的名称。 =
