UI timeout page that the user is redirect to instead of leaving them "wherever" they are to have a fail on "first click"

My users (and I ) are often frustrated by the "CSRF warning" only to click a link and SSO back into the app. It would be a much better experience if the user would come back to a "your session has expired" page and know that the first click leads to a login process instead of being surprised by the process.

I have seen "security centric" apps that have UI timeouts built in.

When the timeout expires ( due to lack of use ) the browser auto redirect the user to a page that tells them their session has timed out and gives them a link to log back in. (and start a new session.)

I think it would be a good feature for Grouper UI to implement.
