I tried to put this question directly to email@example.com
(this address comes from the mailto: tag on the bottom of the page at:
http://www.webdav.org/goliath/) but the message was bounced. If
anyone here can forward this to Thomas, I would appreciate it.
As well, if anyone here can reply to any of all of this query,
that would be appreciated too.
Thanks in advance for any help on this.

In our university system (Georgia), we
use an enterprise level Learning Management System called "WebCT
Vista" which supports WebDAV in addition to traditional/classic
HTTP upload methods (see
I'm one of the few Vista Institutional
Admins who are also Mac users so have been asked to look into problems
that have been reported by Mac users of the system and investigated by
WebCT technical support personnel (see report quoted
Goliath was identified as a solution to
a problem with the MacOS X client having to do with its behavior in
updating files that have been modified (e.g. edited).
Apparently, the MacOS X client deletes and recreates the file which
destroys important metadata on the server (IMS ContentID) and Goliath
(as well as many other WebDAV clients) does not.
Unfortunately, we cannot use Goliath
instead of the MacOS X client because port 21 is not available to our
students (fire wall) and is needed by Goliath. This claim seemed
strange to me because I had thought that all WebDAV clients used HTTP
port 80 alone. Is this not the case?
WebCT Vista operates a bit differently
than most other WebDAV-enabled servers in that it generates the URI
that client apps need. Here's an actual
Obviously, the length and complexity of
these URIs makes such a practice necessary.
Now for my question.
As far as you know, are the statements
below accurate? Whatever insights you'd care to share will be

Mac Finder's functionality causes it
to delete and recreate a file when
uploading an updated version. As a result, the Content ID of the
will change, and all links to that file will be broken. This is an
issue with Mac Finder.
Goliath, a WebDAV client for Macintosh, does not have this issue,
was recommended to be used instead of Mac Finder. However, Goliath
not function correctly with Georgia's Vista instance because it needs
work through port 21, which is blocked at the firewall.
Mac Finder's WebDAV behaviour does not match
that of any other WebDAV client we have tested with. Finder is
one I know of so far that deletes and recreates a brand new file when
an updated version of a file. All other tested WebDAV clients
existing file on the server and replace the contents. Given that
have Partner, or Higher Escalation status with Apple, a possible
solution is to
have both USG and WebCT log a ticket with Apple Customer Support on
issue. Depending on how much hardware and software that is
deployed on the Georgia campuses, USG may have more influence than
