[Zope] Zope Session Timeout

[Asad Habib]

Does anyone know how to check if a Zope Session has timed out? I know that
this value is set in the Session Data Container object that resides in the
Temp folder at the root level. But how can I check to see if this time
limit has been exceeded? I would like to redirect the user to a customized
error page when this happens. Any help would be greatly appreciated.
Thanks.
