Redirect to Portal Login page from portlet

Question

We have lots of applications on the portal and many of them need the logged in user information to provide the right display context. For example, "My Notes" where notes are stamped with the user's login id. Our portlet applications show exception messages when the user id is unavailable. Pressing a refresh button takes them to the portal login page.
Does anyone know how to redirect to the portal login page? Here is how I would like it to work: A user has the application up beyond the session timeout period and does something that causes the page to submit. At the application server we look for the logged in user ID which is missing due to session timeout and we send them to the portal login page.
Thanks! Mike

Hi James,
<br />
<br />I fear this isn´t possible to do with ADDT, as it will - when using its Restrict Access To Page behaviour - always redirect to the page you specified in the Control Panel.
<br />
<br />However you can help yourself with a simple custom PHP redirect script
<i>(place it @ @ line 1 of your document)</i> which checks whether the "kt_login_id" Session Variable is set, and if it´s not set, redirect to a different login page:
<br />
<br /><?php<br />if (!isset($_SESSION['kt_login_id'])) {<br />header('Location: http://www.example.com/directory/login.php') ;<br />}<br />?>
<br />
<br />Hint: users who login via a different login page will still be redirected to ADDT´s default login page when logging out
