诡异的代码

我不知道怎么选择代码啊 我的这个文件是JSP的文件 
 代码如下:
<%@ page contentType="text/html" pageEncoding="GBK"%>
<html>
<head>
<title>设置cookie保存的时间</title>
</head>
<body>
<%
Cookie c1=new Cookie("lxh","李兴华");
Cookie c2=new Cookie("mldn","www.baidu.com");
c1.setMaxAge(60);
c2.setMaxAge(60);
// response.addCookie(c1);
response.addCookie(c2);
%>
</body>
</html>
不知道为什么 同样的代码 response.addCookie(c2);的话 就可以 但是把c1也添加进去的话 就报错 就是注释掉的那行 那位大侠帮忙解决下  这是什么原因呢?

  1.   

    <%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
    <%@page import="java.net.URLEncoder"%>
    <%
    String path = request.getContextPath();
    String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
    String name="李兴华";
    name=URLEncoder.encode(name,"utf-8");
    Cookie c1=new Cookie("lxh",name);
    Cookie c2=new Cookie("mldn","www.baidu.com");
    c1.setMaxAge(60);
    c2.setMaxAge(60);
     response.addCookie(c1);
    response.addCookie(c2);
    %>可先把存储的中文用utf-8编码一下。。
    name=URLEncoder.encode(name,"utf-8");

    就是编码的问题，写cookie必须注意编码
      

  5.   

    java.lang.IllegalArgumentException: Control character in cookie value, consider BASE64 encoding your value给你报的错啊！！
