Hi All,
I have used simple JSP and java files to build my application. All the jsp files have included a 'header.jsp' file, in which there is a Log Out image button. After clicking this button, the page 'logOut.jsp' emerges. In this page, I am invalidating the session. But when I click either back button of IE, or 'backspace' key, I can still access all the pages.

I have used

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

and

<%response.setHeader("Cache-Control","no-cache");%>
<%response.setHeader("expires","0");%>
<%response.setHeader("Pragma","no-cache");%>

in all the pages to clear all the cache.

Please help me expire the pages once logged out.

Thanks in Advance......!

when the user is login to your application store that username in session.
And in header.jsp check for not null aginst that session username object.

Hi

<%response.setHeader("Cache-Control","no-cache");%>
<%response.setHeader("expires","0");%>
<%response.setHeader("Pragma","no-cache");%>
----------------------------------------
looks good. you have to do some more work.you can not disable browser back button.but you can controll also you can disable right click and backspace button through java script...

for your problem ,there are many solution in javascript.
