3 | * CalDAV Server - handle DELTICKET method in line with defunct proposed RFC |
---|
4 | * from: http://tools.ietf.org/html/draft-ito-dav-ticket-00 |
---|
5 | * |
---|
6 | * Why are we using a defunct RFC? Well, we want to support some kind of system |
---|
7 | * for providing a URI to people to give out for granting privileged access |
---|
8 | * without requiring logins. Using a defunct proposed spec seems better than |
---|
9 | * inventing our own. As well as Xythos, Cosmo follows this specification, |
---|
10 | * with some documented variations, which we will also follow. In particular |
---|
11 | * we use the xmlns="http://www.xythos.com/namespaces/StorageServer" rather |
---|
12 | * than the DAV: namespace. |
