用sendRedirect跳转

3.用sendRedirect跳转：

response的方法：void sendRedirect(String url)，将页面重定向到指定的URL地址上。

例：3.3.1

package com;

import java.io.IOException;

import javax.servlet.ServletException;

import javax.servlet.http.HttpServlet;

import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;

public class DeleteCookie extends HttpServlet {

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

response.sendRedirect("http://localhost:8080/ServletHello/cookie.html");

System.out.println("ok");

}

}
