2.2.1.3 Moss-Did Header

A WebDAV client SHOULD NOT include the Moss-Did header in any HTTP 1.1 requests.<3>

If this header is included, it MUST contain a curly braced GUID String. It is identical to the moss-uid header. This new header is specified as follows:

 Moss-Did Header = "moss-did" ":" Curly Braced GUID String

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