I'd like to oppose, can I? :)

I could imagine application which has one and only continuation per
client. In this scenario, when client hits "Back" button, application
shows to the user *same*, *current* page but not *previous* page.

If you add continuation persistence on server side... In *this*
scenario, cookies *do* make sense. Don't you agree?

Just suppose for a moment that your app requires one and only
continuation.


Mmm... I already see where it can be used... :)
