Namespace:

System.Web

Assembly:

System.Web.dll

Encapsulates the HTTP intrinsic object that contains methods for setting cache-specific HTTP headers and for controlling the ASP.NET page output cache.

HttpCachePolicyWrapper

Remarks

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.

Constructors

HttpCachePolicyWrapper(HttpCachePolicy)

Initializes a new instance of the HttpCachePolicyWrapper class.
