Salut Vincent,

I have never done it, but here is what I would try.

Subclass WAApplication making sure you re-implement #description on  
the class side.
Then recreate your Seaside app using config and selecting the new  
WAApplication subclass
in the "type" selection list. This can surely be done  
programmatically as well.
Once this is done, you will be able to re-implement  
#handleExpiredRequest: to your liking.

Best luck,
