    Console.WriteLine("Host name: {0}", request.UserHostName);
    Console.WriteLine("Host address: {0}", request.UserHostAddress);
    Console.WriteLine("User agent: {0}", request.UserAgent);
}

Public Shared Sub ShowRequestProperties1(ByVal request As HttpListenerRequest)
    ' Display the MIME types that can be used in the response.
    Dim types As String() = request.AcceptTypes

    If types IsNot Nothing Then
        Console.WriteLine("Acceptable MIME types:")

        For Each s As String In types
            Console.WriteLine(s)

Keterangan

Header Accept adalah string nama jenis Multipurpose Internet Mail Extensions (MIME) yang dipisahkan spasi (misalnya, image/jpeg), yang menunjukkan jenis MIME yang disiapkan untuk diterima dan diproses klien dalam respons. Entri */* menunjukkan bahwa klien menerima jenis MIME apa pun. Untuk deskripsi terperinci tentang Accept header, lihat RFC 2616, tersedia di https://www.rfc-editor.org.

Untuk daftar lengkap header permintaan, lihat HttpRequestHeader enumerasi.
