Attributes: ComVisibleAttribute

Remarks

In most cases, your code will not deal with HttpWorkerRequest directly because request and response data are exposed through the HttpRequest and HttpResponse classes. Some internal ASP.NET classes extend this class. If your code implements its own hosting environment, it will need to extend this class to call the ProcessRequest method. In addition, your code could create a derived class for the purpose of child-request execution within a given application in order to pass its instance to ProcessRequest. In this case, the derived class should keep a reference to the current HttpWorkerRequest and delegate most of the methods to it.

Constructors
