首先上2段简单的代码
seed.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>种植cookie</title> </head> <body> <% Cookie cookie = new Cookie("cookie-name","nimei"); response.addCookie(cookie); out.println("nimei"); %> </body> </html> list.jsp <%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>列出cookie</title> </head> <body> <% Cookie[] cks = request.getCookies(); for (Cookie ck : cks) { out.println(ck.getName()); } %> </body> </html> 首先准备2台tomcat访问：http://localhost:8080/seed.jsp初始化cookie
随后访问：
http://localhost:8080/list.jsp
http://localhost:8081/list.jsp
