[quote author="dotmundo" date="1277950699"]Silly question regarding the 'is_logged_in' function. Will it return FALSE if the user's session expires? By that I mean is when a user authenticates, goes off to the bathroom and comes back after the session expiration time has expired, can I use that function to force him to re-authenticate again?[/quote]
Yes. You can also change the $config['login_attempt_expire'] as you wish.
