[Zope] WebDAV Locks - MS Office 2000

Hi Chris, last month, you reported problems with Office 2000 and Zope. We now run into apparently the same problem. I also found Werner's excellent analysis of your problem. I was puzzled by the strange, surely non-standard, "Ms-Author-Via: DAV" header in the "OPTIONS" output. The source documentation suggests it is "an borg-specific header for ie5". I am (almost) convinced that this header is responsible for Office 2000 trying to open the documents via WebDAV. I will remove this header (set in "webdav.Resource.OPTIONS") in our installation because we do not use Office 2000 for authoring Zope content. Maybe, this is an option for you, too. Dieter
