Forum OpenACS Development: Re: oacs-dav not working with NaviServer 4.99.8
However, when starting from a version that is already broken, then "getting WebDAV" to work is probably by far a larger project than it might look like at the first glance. If the WebDAV code was not touched since 10 years, it probably needs various more changes and a lot of testing to work well on today's OSes. Handling of WebDAV was traditionally quite different under windows as it was under Mac OS X or Linux. Such a project should be probably done by someone having Windows on his desktop.
