HttpVersion Class

Defines the HTTP version numbers that are supported by the HttpWebRequest and HttpWebResponse classes.

Namespace:  System.Net
Assembly:  System (in System.dll)
public class HttpVersion

The HttpVersion class defines the HTTP versions that are supported by the HttpWebRequest and HttpWebResponse classes. The HTTP version number is used to control version-specific features of HTTP, such as pipelining and chunking.

The following example demonstrates the use of HttpVersion.

			// Create a 'HttpWebRequest' object.
			HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("http://www.microsoft.com");
			Console.WriteLine("\nThe 'ProtocolVersion' of the protocol before assignment is :{0}",myHttpWebRequest.ProtocolVersion);
			// Assign Version10 to ProtocolVersion.
			myHttpWebRequest.ProtocolVersion=HttpVersion.Version10;
			// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
			HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
			Console.WriteLine("\nThe 'ProtocolVersion' of the protocol after  assignment is :{0}",myHttpWebRequest.ProtocolVersion);
			Console.WriteLine("\nThe 'ProtocolVersion' of the response object is :{0}",myHttpWebResponse.ProtocolVersion);
// Create a 'HttpWebRequest' object.
HttpWebRequest* myHttpWebRequest =
   dynamic_cast<HttpWebRequest*>(WebRequest::Create(S"http://www.microsoft.com"));
Console::WriteLine(S"\nThe 'ProtocolVersion' of the protocol before assignment is : {0}",
   myHttpWebRequest->ProtocolVersion);
// Assign Version10 to ProtocolVersion.
myHttpWebRequest->ProtocolVersion=HttpVersion::Version10;
// Assign the response Object* of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse* myHttpWebResponse=dynamic_cast<HttpWebResponse*>(myHttpWebRequest->GetResponse());
Console::WriteLine(S"\nThe 'ProtocolVersion' of the protocol after  assignment is : {0}",
   myHttpWebRequest->ProtocolVersion);
Console::WriteLine(S"\nThe 'ProtocolVersion' of the response Object* is : {0}",
   myHttpWebResponse->ProtocolVersion);
