jsp頁面設置no-cache

 

<%@ page language="java" buffer="none" contentType="text/html; charset=UTF-8" %>
第一行里加入buffer="none",然後再添加以下代碼
    if(request.getProtocol().compareTo("HTTP/1.0")==0){
        response.setHeader("Pragma","no-cache");   
    }else if(request.getProtocol().compareTo("HTTP/1.1")==0){
        response.setHeader("Cache-Control","no-cache");   
    }
    response.setDateHeader("Expires",0);
