CacheItemRemovedCallback

Synopsis

Functions with the CacheItemRemovedCallback signature can be used to respond to the onRemoveCallback event when an item is dropped from the cache. For example, this could allow you to perform related cleanup tasks. You are provided with the cache object, its key, and the reason why it was removed (using the CacheItemRemovedReason enumeration).

To use this event, pass the function name as an argument in the Cache.Insert() method.

        ByVal key As String, ByVal value As Object, 
        ByVal reason As CacheItemRemovedReason)
