Page expires on Browser back

[Gavi Raaghav]

We have a web application.When the user traverses from JSP A to JSP B and then clicks the browser back button to goto A the page cannot be displayed screen appears,however if then the user clicks the refresh button and submits the page then then page A gets displayed properly.What is the fix for the back button to behave correctly that is without refresing the page shud get displayed.
I am using IE6.0,WAS5.1 and using cookies for Session Management in WAS

Personally I would say that that is the appropriate behavior. Unlike static web sites, web applications should expire pages immediately so that the back button cannot be used to show data that could be stale.

But we have a requirement to do the same.Can something be done in the code or configuration to achieve this?
