盗用连接 技术

其实很简单

就是利用response 的  头属性来获取客户端 连接到服务端 连接地址

如果连接过来的非本网页地址 的话！ 就直接返回到主页去

package com.renxing.Servlet;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class indexServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException
{
  //盗用连 可以通过 客户端的request 来获取相关的方法 来判断 用户从什么地址连接过来的
  //如果非指定地址可以通过 response蹦到主页 重新看正版的
  String referer=request.getHeader("referer");
  if(referer==null||!referer.startsWith("http://localhost:8080"))
  {
   response.sendRedirect("/mail/index.jsp");
   System.out.println(referer);
   return;
  }
  request.getRequestDispatcher("/servlet/HeadServlet").include(request, response);
  request.getRequestDispatcher("/servlet/FootServlet").include(request, response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException
{
  doGet(request, response);
}
}


请求包含

也就是说 在意个页面中要包含这2个内容

  request.getRequestDispatcher("/servlet/HeadServlet").include(request, response);
  request.getRequestDispatcher("/servlet/FootServlet").include(request, response);

请求调转 forward

  request.getRequestDispatcher("/servlet/HeadServlet").forward(request, response);
  request.getRequestDispatcher("/servlet/FootServlet").forward(request, response);
