title: Cache Expiration event asp.net enterprise library
body: <p>I wanted to know if there is any event which occurs each time a cache item is about too get expired or any event which is raised when a cache item is getting expired.I am using enterprise library in asp.net for caching.I want to store some data in my database when a cache is about to get expired instead of calling a function or invoking an event myself I was thinking of using the already managed cache library event which is being used to flush or dispose cache items.</p>
