Surely this should be corrected: ?? -------------------------------------------------- http://www.zope.org/Members/michel/ZB/Preface.html Chapter 8: Advanced Zope Scripting This chapter covers scripting Zope with Python and Perl. In it we cover how to write business logic in Zope using more powerful tools than DTML. It discusses the idea of methods in Zope, and focuses on Python and Perl methods. This chapter shows you how to add industrial-strength scripting to your site. -------------------------------------------------- best wishes - Jason ___________________________________________________________ Jason CUNLIFFE = NOMADICS['Interactive Art and Technology']

Not sure about Zopes supprot and not > sure if I like the protocol on production servers anyway ;-) For standard GET and PUT requests, WebDAV is indistiguishable from "normal" HTTP.

I meant to paste this link in the last posting. I had the wrong title. http://lists.zope.org/pipermail/zope/2000-December/036772.html And when do I get my book? And can I get the likes of Guido, and Jim to sign the book also? Just making sure this thing is on. -Jimbo
