Correct.  Zope's WebDAV machinery looks for a method called 'PUT_factory'
when a PUT is done to a non-existent resource.  If found, the NullResource
calls the method, passing the name, content type, and body of the PUT;  the
method is expected to instantiate and return a new object of an appropriate
type, which the NullResource then sticks into its own slot in its folder and
hands off the remainder of the PUT.

I can't reproduce this at all.  I edited CMFCore.PortalFolder.py, and
added the following line at the beginning of PortalFolder.PUT_factory:

   import pdb; pdb.set_trace()

When I run Zope in debug mode, and FTP into a CMFSite, any PUT operation
to a new filename triggers the breakpoint.
