We don't support WebDav on our shared hosting
platform. The problem being the management of the accounts and
necessary ACL permissions are not integrated through our Control Panel.
We would suggest using FTP instead. It is possible to automatically
login to FTP. You can do this by passing the username and password for
FTP in a URL and make a shortcut on your desktop:
e.g "ftp://username:password@ftp.your_domain.com"
