I have had alot of fun with this area already....
If you are using JSP pages set the response headers within the JSP page - >
<%
response.setHeader("Cache-Control", "no-cache");
response.setHeader("Pragma", "no-cache");
response.setHeader("Expires", "Sat, 01 Jan 2000 06:01:01 GMT");
%>
This is better than using straight META tags as with IE5 it loads the page
into cache before interpretting the page. Try not to use both, setting the
response headers and using META tags for the same values as you get mixed
results.
When the user logs out invalidate the session.
Now in theory this should work but you get mixed results depending on the
Browser especially IE5 and above which seems to still cache everything
regardless. However on installing a certificate IE appears to behave itself.
Hope this helps
