Note: This precondition actually violates the requirement earlier in the text that a server support cyclic bindings. But probably a server should be allowed to reject cyclic bindings, so I'm happy to add this pre-condition (and remove the current requirement), if nobody objects.

Any discussion of 14.4_CLARIFY_VH_DELETE_2 should be mailed to the deltav mailing list, not to the general webdav mailing list. For the binding spec, Julian asks for two new preconditions for BIND, which I will go ahead and add, unless someone objects (they both seem reasonable to me). Any discussion of these two new preconditions for BIND should be mailed to the general webdav mailing list. Cheers, Geoff -----Original Message----- From: Julian Reschke [mailto:julian.reschke@gmx.de] ... The issue here is that if we allow a DELETE to fail because other bindings exist, a client may never be able to delete a binding (because due to race conditions, there will always be additional bindings left). I'm not saying that this can be avoided, however it *really* sounds ugly. As I said, I haven't seen a convincing argument why we need this restriction in RFC3253 (and yes, this discussion should be moved to the other mailing list). > Can we agree that servers can reject DELETE/MOVE requests and move the > versioning specific discussion to the versioning mailing list? Yes. Still, we may have to define additional precondition values for - resource does not support additional bindings - new member name can't be used (in deltav: because it was already used for a stable URI) Julian -- <green/>bytes GmbH -- http://www.greenbytes.de -- tel:+492512807760
