When user presses the back button of browser, and does some operation and
presses submit or other button, the request will go to server. And before
trying anything you should always check if user is in session or not, else
redirect him to the login page.
Client browser can override the attributes as described below. But you
should also use them

You will need to set the appropriate HTTP header attributes to prevent the
dynamic content output by the JSP page from being cached by the browser.
Just execute the following scriptlet at the beginning of your JSP pages to
prevent them from being cached at the browser. You need both the statements
to take care of some of the older browser versions.
<%
response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy
server
%>
If the above fails, try changing the first line to
response.setHeader("Cache-Control","no-store"); //HTTP 1.1

Subject: JSP page refresh option
Is there any way for me to have my page refreshed
everytime it is opened on the browser?
I am working on a database backed web project, with
JSP as front end and Oracle, JDBC as the back end.
When I have a particular user "logout" of the system,
it is noticed that simply by hitting the "back" button
on the web browser, one is able to view and act upon
the previous pages.
session.invalidate is already implemented. I need a
way to refresh the page.
I'd appreciate any feedback at the earliest.
Thanks,
Saket
