[Catalyst] Check session expiry without extending it

[John Karr]

Never mind, that's too simple. It breaks if users open up multiple pages unless you increase the refresh to just over twice the timeout, which may be an issue since presumably you don't want your user's expired sessions hanging around in their browser. 

Even simpler put a refresh tag in the page with a refresh a little over the session timeout value, then the site's handler for expired sessions can do the rest.

Why not return the datetime when the session expires with every page and
have a client-side js that does the redirect without hammering the
server?
