HttpWebRequest.Pipelined Property

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

[Visual Basic]
Public Property Pipelined As Boolean
[C#]
public bool Pipelined {get; set;}
[C++]
public: __property bool get_Pipelined();
public: __property void set_Pipelined(bool);
[JScript]
public function get Pipelined() : Boolean;
public function set Pipelined(Boolean);

Property Value

true if the request should be pipelined; otherwise, false. The default is true.

Remarks

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.

Example

[Visual Basic, C#, C++] The following example prints the value of the Pipelined property to the console.
