public abstract class HttpCachePolicyBase

The HttpCachePolicyBase class is an abstract class that contains the same members as the HttpCachePolicy class. The HttpCachePolicyBase class lets you create derived classes that are like the HttpCachePolicy class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members with customized behavior that fulfills the scenario you are testing.

The HttpCachePolicyWrapper class derives from the HttpCachePolicyBase class. The HttpCachePolicyWrapper class serves as a wrapper for the HttpCachePolicy class. At run time, you typically use an instance of the HttpCachePolicyWrapper class to call members of the HttpCachePolicy object.

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