设置HTTP header方式

一， Server Code

JSP---->

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%> 

Java---->

 <%
 response.setHeader("Cache-Control","no-store");
 response.setContentType("text/html;charset=UTF-8");
 response.setHeader("Pragma","no-cache");
 response.setDateHeader ("Expires", 0);
 %>

二，HTML meta标签

 <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

 <meta charset="utf-8" />

三， JS设置requrest Header

 xmlhttp.setRequestHeader("Accept", "*");
