I’ve written a simple, multi-page Rails app which works fine except for
one thing: often when my users click the browsers BACK button, they
receive the “Warning: Page has Expired” message in IE, with the
suggestion to hit the refresh button. If they do hit refresh, they are
told that the information will be sent back to the page, and they have
to hit “Retry” to proceed.
I have no idea where to begin looking for this problem. Any ideas? Is
there a timeout parameter somewhere…?
