HttpWebRequest.Referer Property

Gets or sets the value of the Referer HTTP header.

Namespace:  System.Net
Assembly:  System (in System.dll)
public string Referer { get; set; }

Property Value

Type: System.String
The value of the Referer HTTP header. The default value is null.

If the AllowAutoRedirect property is true, the Referer property is set automatically when the request is redirected to another site.

To clear the Referer HTTP header, set the Referer property to null.

NoteNote

The value for this property is stored in WebHeaderCollection. If WebHeaderCollection is set, the property value is lost.

The following code example sets the Referer property.

			// Create a 'HttpWebRequest' object.
			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);
