Cancels a request to an Internet resource.
Assembly: System.Net (in System.Net.dll)
The method cancels a request to a resource. After a request is canceled, calling the BeginGetResponse, EndGetResponse, BeginGetRequestStream, or EndGetRequestStream method causes a WebException with the Status property set to RequestCanceled.
In the case of asynchronous requests, it is the responsibility of the client application to implement its own time-out mechanism.
