HttpWebRequest.Pipelined プロパティ
インターネット リソースへの要求をパイプライン処理するかどうかを示す値を取得または設定します。
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);
プロパティ値
要求をパイプライン処理する場合は true 。それ以外の場合は false 。既定値は true です。
解説
アプリケーションは Pipelined プロパティを使用して、パイプライン経由の接続に関する設定を示します。 Pipelined が true の場合、アプリケーションは、それらをサポートするサーバーへのパイプライン接続を行います。
さらに KeepAlive プロパティが true の場合に限り、パイプライン接続を行います。
使用例
[Visual Basic, C#, C++] Pipelined プロパティの値をコンソールに出力する例を次に示します。
