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

Examples

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

// Create a 'HttpWebRequest' object.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( myUri ) );
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
// Display the contents of the page to the console.
Stream^ streamResponse = myHttpWebResponse->GetResponseStream();
StreamReader^ streamRead = gcnew StreamReader( streamResponse );
array<Char>^ readBuffer = gcnew array<Char>(256);
int count = streamRead->Read( readBuffer, 0, 256 );
Console::WriteLine( "\nThe contents of HTML page are......." );
while ( count > 0 )
{
   String^ outputData = gcnew String( readBuffer,0,count );
   Console::Write( outputData );
   count = streamRead->Read( readBuffer, 0, 256 );
}
Console::WriteLine( "\nHTTP Request  Headers :\n\n {0}", myHttpWebRequest->Headers );
Console::WriteLine( "\nHTTP Response Headers :\n\n {0}", myHttpWebResponse->Headers );

streamResponse->Close();
// Release the response object resources.

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

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.
