Contoh kode berikut menunjukkan penggunaan properti ini.

public static void ShowRequestProperties2 (HttpListenerRequest request)
{
    Console.WriteLine("KeepAlive: {0}", request.KeepAlive);
    Console.WriteLine("Local end point: {0}", request.LocalEndPoint.ToString());
    Console.WriteLine("Remote end point: {0}", request.RemoteEndPoint.ToString());
    Console.WriteLine("Is local? {0}", request.IsLocal);
    Console.WriteLine("HTTP method: {0}", request.HttpMethod);
    Console.WriteLine("Protocol version: {0}", request.ProtocolVersion);
    Console.WriteLine("Is authenticated: {0}", request.IsAuthenticated);
    Console.WriteLine("Is secure: {0}", request.IsSecureConnection);
}

Public Shared Sub ShowRequestProperties2(ByVal request As HttpListenerRequest)
    Console.WriteLine("KeepAlive: {0}", request.KeepAlive)
    Console.WriteLine("Local end point: {0}", request.LocalEndPoint.ToString())
    Console.WriteLine("Remote end point: {0}", request.RemoteEndPoint.ToString())
    Console.WriteLine("Is local? {0}", request.IsLocal)
    Console.WriteLine("HTTP method: {0}", request.HttpMethod)
    Console.WriteLine("Protocol version: {0}", request.ProtocolVersion)

    Console.WriteLine("Is secure: {0}", request.IsSecureConnection)
End Sub

Keterangan

Jika klien dan server HTTP berharap untuk bertukar data beberapa kali dalam waktu singkat, koneksi persisten mempercepat komunikasi mereka dengan memungkinkan mereka menghindari overhead yang diperlukan untuk membuka dan menutup koneksi TCP untuk setiap pesan. Untuk klien yang menggunakan HTTP/1.1, nilai default untuk properti ini adalah true.
