Odesílatel: Sinclair <fred.duwez@freesurf.fr> OK, but with Zope, you can build a application controller who call decode parameters and call the real zope object. Or a simple page page controller who encrypt his parameters :

Example : a document has url : $ZOPE/.../document_manager/document_37.

I wish the displayed url looks like : $ZOPE/.../document_manager?document=k2316fge54dsgb51v3vsdv4

That is the document_manager who translates an unreadable parameter to document real url.

Unreadable? Not available... But you could use POST request method with use of hidden form field. But I have tool for download these pages too. So you will block only lamers, some search engines does hidden fields form submitting too. Regards JL.
