[Zope] Traversal question

[David Pratt]

Hi Jonathan.  Thank you for your reply. The ? = & don't make for very  
friendly or future proof urls.  I have thought of this possibility you  
have suggested but thought there might be a way to do this with  
traversal.  I read a tutorial by Chris McDonough getting rid of the ? =  
& appeared to be one of the goals of using zope's traversal. I am   
exploring the possibilities of getting rid of the ? = &  in my  
application.

Regards,
David
