通过response的addcookie方法将其发送到客户端

<html><head><meta http-equiv="Content-Type" content="text/html; charset=UTF-8"><title>show the newfile1</title></head><body>      <%        String name=request.getParameter("name");        String brithday=request.getParameter("brithday");        String mail=request.getParameter("mail");        Cookie myCook=new Cookie("mrCookInfo",name+"#"+brithday+"#"+mail);        myCook.setMaxAge(60*60*24*365);            //设置cookie有效期        response.addCookie(myCook);      %>                     表单提交成功      <ul style="line-height:24px">           <li>姓名:<%=name %>           <li>生日:<%=brithday %>           <li>电子邮箱:<%=mail %>           <li><a href="index.jsp">返回</a>      </ul></body></html>
