public abstract class HttpRequestBase

The HttpRequestBase class is an abstract class that contains the same members as the HttpRequest class. The HttpRequestBase class enables you to create derived classes that are like the HttpRequest 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 that have customized behavior that fulfills the scenario that you are testing.

The HttpRequestWrapper class derives from the HttpRequestBase class. The HttpRequestWrapper class serves as a wrapper for the HttpRequest class. At run time, you typically use an instance of the HttpRequestWrapper class to invoke members of the HttpRequest 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.
