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
