[Zope] Traversal question

[Pascal Peregrina]

Traversal is not meant to have pretty urls.

To do such, I would either :
- add a Site Access Rule in the root folder that would rewrite the url from
the "nice" form to the physical location of the script and add the
parameters to the request object. 
- use Apache in front of Zope and some mod_rewrite magic

I am sure you don't want to hear this, but that's what '? = &' are for.  If 
you really want to make your life complicated you could look into storing 
the parameters in cookies or session data, but those are pretty ugly 
work-arounds just so you can have pretty urls.
