Oh, geez. What has this list come to. Three replies, and three incorrect (or
close to it) answers...

A1: "respond with HTTP/1.1"
--> well, this is obviously not a prerequisite because we see that Web
    Folders *does* end up doing a PROPFIND. So it obviously doesn't mind.

A2: "use 'DAV :1.1' and 'MS-Author-Via: DAV'"
--> the former should be the 'DAV: 1,2' header and the latter is not
    required (it simply optimizes out a round trip). We also see in the log
    below that Anton returns those for the /DAV directory.

A3: "return MKCOL and PROPFIND in the OPTIONS response"
--> he is returning PROPFIND (but not MKCOL). Web Folders doesn't need the
    MKCOL... it already believes there is a DAV server there by the simple
    evidence that it issues a PROPFIND.


Sigh. Yes, using HTTP/1.1 in the response is a good idea and is technically
required (and it will help with connection persistence and request
pipelining). But it isn't a precondition. It would be good to return MKCOL,
too. I'd also suggest getting rid of that Status: header (it's useless).

I believe your real problem exists in the Multistatus response. You are
using the "DAV" namespace *prefix*, but have not placed the elements into
the "DAV:" *namespace*. Change your outermost element to:

<DAV:multistatus xmlns:DAV="DAV:">

That should hopefully do the trick. I haven't thoroughly analyzed the body
of your multistatus, but a rough glance seems to show it is okay.

Also, have you seen the Slide project? http://jakarta.apache.org/slide/
Or the Magi-DAV project? http://magi.endeavors.org/

Cheers,
