Некоторые вопросы о записи на ответном потоке ASP.NET

Я нашел способ получить имя клиентской машины.

public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException { 

    Logger.getLogger(this.getClass()).warning("Inside Confirm Servlet");  
    response.setContentType("text/html");

    String hostname = request.getRemoteHost(); // hostname
    System.out.println("hostname"+hostname);

    String computerName = null;
    String remoteAddress = request.getRemoteAddr();
    System.out.println("remoteAddress: " + remoteAddress);
    try {
        InetAddress inetAddress = InetAddress.getByName(remoteAddress);
        System.out.println("inetAddress: " + inetAddress);
        computerName = inetAddress.getHostName();

        System.out.println("computerName: " + computerName);


        if (computerName.equalsIgnoreCase("localhost")) {
            computerName = java.net.InetAddress.getLocalHost().getCanonicalHostName();
        } 
    } catch (UnknownHostException e) {

        }

    System.out.println("computerName: " + computerName);
}
