I'm not sure it can be done. Access doesn't recognize the http protocol (nor
the ftp protocol, for that matter). If you can't map to a share on the
server, you may be out of luck.
Carl Prothman has some information about the Microsoft Remote Provider at
http://www.able-consulting.com/MDAC/ADO/Connection/MSRemote.htm
You might be able to get this to work, but read the notes Carl has on that
page: RDS is consider obsolete by Microsoft, and there can be serious
security issues using it.
