[Catalyst] Check session expiry without extending it

[Steve Kleiman]

Using Catalyst::Plugin::Session with Session::State::Cookie.

Would like to be able to poll server if the user's session has expired WITHOUT extending the session itself.

The objective is to have a javascript periodical executor check if a session is expired and redirect user to a "Your session has expired" page if appropriate. Could do it in javascript but would prefer doing it on server.

Anyone tried this?

Thanks in advance.
