I want to avoid an item being removed from cache when expire in SOME OCASIONS

If i understand how CacheItemUpdateCallback works, i need to asign to expensiveObject the new object, in my case: the old one. But i cant access the item with HttpContext.Current.Cache[key],

my question: how to access it? or in other words, How avoid this item being removed.?
