No. WebDAV imposes restrictions on accessing contents of the folders. You won't be able to do anything with it by shell or FTP. It is owned by dhapache and the permissions are very restrictve.
You can make the contents of a WebDAV folder accessible to the web (HTTP) with optional password protection, however you will not be able to execute CGI scripts or programs. Again, the contents will not be accessible by FTP at all.
