关于JSP网页有效期，急！

response.setHeader("Cache-Control","no-store");
response.setHeader("Pragma","no-cache");
response.setDateHeader("Expires",0);

解决方案 »

  1.   

    不使用户缓存可以按楼上的啊,response.setHeader("Cache-Control","no-store");
    response.setHeader("Pragma","no-cache");
    response.setDateHeader("Expires",0);要是用了STRUTS架构,你只要在actionservlet中加入这些东西就可以了要不然你要每页都要加
      

  2.   

    就是这个
    response.setHeader("Cache-Control","no-store");
    response.setHeader("Pragma","no-cache");
    response.setDateHeader("Expires",0);
      

  3.   

    <html>
      <head>
            
        <title>My JSP 'MyJsp.jsp' starting page</title>
        
        <meta http-equiv="pragma" content="no-cache">
        <meta http-equiv="cache-control" content="no-cache">
        <meta http-equiv="expires" content="0">
            
          </head>
      
      <body>
        This is my JSP page. <br>
      </body>
    </html>
