Exemplos

Este exemplo cria uma HttpWebRequest consulta e para um HttpWebResponse. O exemplo verifica então se o servidor responde com a mesma versão.

Uri ourUri = new Uri(url);
    // Creates an HttpWebRequest for the specified URL.
    HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(ourUri);
    myHttpWebRequest.ProtocolVersion = HttpVersion.Version10;
    // Sends the HttpWebRequest and waits for the response.
    HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();
    // Ensures that only Http/1.0 responses are accepted.
    if(myHttpWebResponse.ProtocolVersion != HttpVersion.Version10)
        Console.WriteLine("\nThe server responded with a version other than Http/1.0");
    else
    if (myHttpWebResponse.StatusCode == HttpStatusCode.OK)
        Console.WriteLine("\nRequest sent using version Http/1.0. Successfully received response with version HTTP/1.0 ");
    // Releases the resources of the response.
    myHttpWebResponse.Close();

Dim ourUri As New Uri(url)
' Creates an HttpWebRequest with the specified URL. 
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create(ourUri), HttpWebRequest)
myHttpWebRequest.ProtocolVersion = HttpVersion.Version10
' Sends the request and waits for the response.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
'The ProtocolVersion property is used to ensure that only Http/1.0 responses are accepted. 
If myHttpWebResponse.ProtocolVersion Is HttpVersion.Version10 Then
    Console.WriteLine(ControlChars.NewLine + "The server responded with a version other than Http/1.0")
Else
    If myHttpWebResponse.StatusCode = HttpStatusCode.OK Then
        Console.WriteLine(ControlChars.NewLine + "Request sent using version HTTP/1.0. Successfully received response with version Http/1.0 ")
