Assembly: System (in System.dll)
is the number of milliseconds that a subsequent synchronous request made with the GetResponse method waits for a response, and the GetRequestStream method waits for a stream. The applies to the entire request and response, not individually to the GetRequestStream and GetResponse method calls. If the resource is not returned within the time-out period, the request throws a WebException with the Status property set to WebExceptionStatus.Timeout.
In the case of asynchronous requests, the client application implements its own time-out mechanism. Refer to the example in the BeginGetResponse method.
To specify the amount of time to wait before a read or write operation times out, use the ReadWriteTimeout property.
A Domain Name System (DNS) query may take up to 15 seconds to return or time out. If your request contains a host name that requires resolution and you set Timeout to a value less than 15 seconds, it may take 15 seconds or more before a WebException is thrown to indicate a timeout on your request.
