If you have set a callback to occur when a cached item is removed,
you will be provided with a CacheItemRemovedReason
argument. The CacheItemRemovedReason will be
Expired if the sliding or absolute expiration time
interval passed, Removed if the object was removed
programmatically with the Cache.Remove( ) method
or by an Cache.Insert( ) method with the same key,
DependencyChanged if the object was invalidated
because of a dependency, or Underused if it has
been removed to free memory.

public enum 
CacheItemRemovedReason  {
Removed = 1 ,
Expired = 2 ,
Underused = 3 ,
DependencyChanged = 4 
}
