[Seaside] [BUG][TEST] #pageExpired

[Lukas Renggli]

Hi Markus,

> I'm curious, for what problem is the trick a solution?

we use it to expire all our old pages when something significantly 
changes in our model. We had problems, because some customers thought 
that they could use the back-button to undelete entities after they 
deleted them. So after such a irreversible operation, we simply expire 
all the pages to avoid errors.

First we tried to use http header-fields to tell browsers not to cache 
our pages, but that did not work properly with Internet Explorer.

Cheers,
Lukas
