Dependency Mechanisms:      Files, SQL Cache Dependency etc This ensures that the cache is re-validated or refreshed once a dependent has changed or been altered 2.  Expire Cache:      The cache will expire after a time frame and the newer items will be added to cache when ever accessed or processed after expiry.  In Cache Expiry, we have the following options 1. Absolute Expiration:   Absolute expiration means It will expire cache after some time period set at the time of activating cache.
