解决servet和jsp中的session不能及时更新的问题

servelt中代码：

 

   session.invalidate();
   session.removeAttribute(CommonUtil.SECURITY_USER);

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

 

jsp页面代码：

 <META HTTP-EQUIV="Pragma" CONTENT="no-cache"> 
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> 
<META HTTP-EQUIV="Expires" CONTENT="0">
