             throws ServletException, IOException {
         response.setHeader("location", "/day06/register.html");
         response.setStatus(302);
         //上面两句代码等同于下面这句代码：
         //response.sendRedirect("/day06/register.html");
 }
     public void doPost(HttpServletRequest request, HttpServletResponse response)
             throws ServletException, IOException {
            doGet(request,response);
