解決servet和jsp中的session不能及時更新的問題

servelt中代碼：

 

   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頁面代碼：

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