PPR and session timeout

[Jeantine Mankelow]

We are using adf's ppr features in our web based product.  This all 
works fine until the session times out and the users tries to do 
something which would cause a ppr on the already loaded page.  To the 
user if appears as if nothing happens, when in fact what is happening is 
the login page is getting rendered in the iFrame.

Any ideas on how we can direct the page the user can see to the login page?
Thanks,
Jeantine
