HttpWebRequest.Abort Method

Cancels a request to an Internet resource.

Namespace:  System.Net
Assembly:  System (in System.dll)

abstract Abort : unit -> unit  
override Abort : unit -> unit

The Abort method cancels a request to a resource. After a request is canceled, calling the GetResponse, BeginGetResponse, EndGetResponse, GetRequestStream, BeginGetRequestStream, or EndGetRequestStream method causes a WebException with the Status property set to RequestCanceled.

The Abort method will synchronously execute the callback specified to the BeginGetRequestStream or BeginGetResponse methods if the Abort method is called while either of these operations are outstanding. This can lead to potential deadlock issues.

In the case of asynchronous requests, it is the responsibility of the client application to implement its own time-out mechanism. The following code example shows how to do this.
