Remarks

The CacheItemPolicy instance contains the expiration details of a cache entry. When the cache object retrieves a cache entry, the policy is checked and if the expiration details is met, the entry is deleted from the cache.

The default constructor of CacheItemPolicy creates a policy that does not expire (maximum value).

CacheItemPolicy supports two types of expiration:

Absolute: The entry will expire at a specific time. To use this set AbsoluteExpiration to the desired date and time and leave SlidingExpiration to the default value of NoSlidingExpiration.
Sliding: The entry will expire if it has not been accessed after for a specific time. To use this set SlidingExpiration to the desired time span value and leave AbsoluteExpiration to the default value of InfiniteAbsoluteExpiration.
