2.2.1.2 Moss-Uid Header

A WebDAV client SHOULD NOT include the Moss-Uid header in any HTTP 1.1 requests.<2>

If this header is included, it MUST contain a curly braced GUID string that represents the current user identifier on the WebDAV client. This new header is specified as follows:

 Moss-Uid Header = "moss-uid" ":" Curly Braced GUID String

Because the server ignores this header, there are no usage specifications for this header.
