Should I create a new CacheItemPolicy for every item I add to a System.Runtime.Caching.ObjectCache?

Question

If by default I want to create a cache where everything expires at 5 am, would I need to create a new CacheItemPolicy for each item that I cache, or would I could a create a default 5 am CacheItemPolicy and reuse it?

Answer 1

If you are using AbsoluteExpiration then you have to create a new one for every item. if you are using SlidingExpiration then a sinple time span might be enough.
