HttpWebRequest.Pipelined Property

Gets or sets a value that indicates whether to pipeline the request to the Internet resource.

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

'Declaration
Public Property Pipelined As Boolean
'Usage
Dim instance As HttpWebRequest 
Dim value As Boolean 

value = instance.Pipelined

instance.Pipelined = value

Property Value

Type: System.Boolean
true if the request should be pipelined; otherwise, false. The default is true.

An application uses the Pipelined property to indicate a preference for pipelined connections. When Pipelined is true, an application makes pipelined connections to the servers that support them.

Pipelined connections are made only when the KeepAlive property is also true.

The following code example prints the value of the Pipelined property to the console.

            ' Create a 'HttpWebRequest' object. 
            Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(myUri), HttpWebRequest)
            ' Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable. 
            Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
            ' Display the contents of the page to the console 
            Dim streamResponse As Stream = myHttpWebResponse.GetResponseStream()
            Dim streamRead As New StreamReader(streamResponse)
            Dim readBuffer(256) As [Char]
            Dim count As Integer = streamRead.Read(readBuffer, 0, 256)
            Console.WriteLine(ControlChars.Cr + "The contents of HTML page are.......")
            While count > 0
                Dim outputData As New [String](readBuffer, 0, count)
                Console.Write(outputData)
                count = streamRead.Read(readBuffer, 0, 256)
