RE: Issue: NEED_FOR_PUTL

We certainly should not restrict the behavior of PUT to only accept
writes if the resource is locked (for the reason given in 2518,
namely interoperability with non-locking clients).  The If header
allows you to specify that a PUT should only succeed if the resource
is locked, so I see no reason to add a PUTL method.

So I agree with Jason's conclusions (i.e. reject this proposal).

Cheers,
Geoff

The description of the issue is:

Is there a need for a PUTL (put which succeeds only if the resource is
locked) method to avoid certain classes of overwrite conflicts, or a need
to
restrict the behavior of PUT on WebDAV servers to only accept writes if the
resource is locked?

Once again, just to get discussion going... I'll note that there hasn't
seemed to be a lot of people asking for this so I'd suggest in the interest
of keeping the spec simple that we defer this proposal until there appears
to be more demand.   The proposal actually provided for an option that
didn't require a change to the functional spec so that remains an option
for those that might later discover that this is important.

I guess I'd consider a proposal to recomend that people lock resources
before they do PUT on them.  I'd actually prefer to not even do that
though. I think we've made the issues clear enough in the spec.  People can
chose to put a lock on the resource if they want.

Other opinions?
