This method can be particularly useful for tracking multiple instances of the System.Web.Caching.CacheDependency class associated with an item or an application.

The identifier is a combination of either the file name (for a file dependency) or the key name (for a cache-key dependency) and a string that this method assigns to the dependency. In classes that derive from the System.Web.Caching.CacheDependency class, you can override this method to customize how it generates the unique identifier.
