public class HttpCachePolicyWrapper : HttpCachePolicyBase

The HttpCachePolicyWrapper class derives from the HttpCachePolicyBase class and serves as a wrapper for the HttpCachePolicy class. This class exposes the functionality of the HttpCachePolicy class while also exposing the HttpCachePolicyBase type. The HttpCachePolicyBase class enables you to replace the original implementation of the HttpCachePolicy class in your application with a custom implementation, such as when you perform unit testing outside the ASP.NET pipeline.


Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
