I'm not sure what you mean by "show" -- where does Zope show you this URL? If you're talking about your browsers address bar, this will be the same as the original request to your product instance, since you are staying within the same HTTP request (when returning the page, instead of redirecting)

Hello Peter, by "show", I mean the URL in browser's address bar. When calling the method defined my product, I come from the URL: http://localhost:8080/MyProductInstance/authors/Add_Author.html So, if I stay in the same HTTP request, shoudn't it be http://localhost:8080/MyProductInstance/authors/Add_Author.html when calling the python method to return the page template ? -nico
