Ejemplos

En el ejemplo de código siguiente se establece la Referer propiedad .

HttpWebRequest	myHttpWebRequest=(HttpWebRequest)WebRequest.Create(myUri);
// Set referer property  to http://www.microsoft.com .
myHttpWebRequest.Referer="http://www.microsoft.com";
// 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 = new StreamReader( streamResponse );
Char[] readBuffer = new Char[256];
int count = streamRead.Read( readBuffer, 0, 256 );
Console.WriteLine("\nThe contents of HTML page are.......");	
while (count > 0)
{
    String outputData = new 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);	
streamRead.Close();
streamResponse.Close();
// Release the response object resources.
myHttpWebResponse.Close();
Console.WriteLine("Referer to the site is:{0}",myHttpWebRequest.Referer);

' Create a 'HttpWebRequest' object.
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(myUri), HttpWebRequest)
' Referer property is set to http://www.microsoft.com
myHttpWebRequest.Referer = "http://www.microsoft.com"
' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
' Displaying 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)
End While
Console.WriteLine(ControlChars.Cr + "HTTP Request  Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebRequest.Headers)
Console.WriteLine(ControlChars.Cr + "HTTP Response Headers :" + ControlChars.Cr + ControlChars.Cr + "{0}", myHttpWebResponse.Headers)
' Release the response object resources.
streamRead.Close()
 streamResponse.Close()
myHttpWebResponse.Close()
Console.WriteLine("Referer to the site is:{0}", myHttpWebRequest.Referer)

Comentarios

Cautela

WebRequest, HttpWebRequest, ServicePointy WebClient están obsoletos y no debe usarlos para el nuevo desarrollo. Use HttpClient en su lugar.

Para borrar el Referer encabezado HTTP, establezca la Referer propiedad nullen .

Nota

El valor de esta propiedad se almacena en WebHeaderCollection. Si se establece WebHeaderCollection, se pierde el valor de la propiedad.
