So what does this mean ? I don't understand it.

It is also a different behavior, depending on the WEB-DAV-server.

Server      Wordocument    HTML
---------------------------------
IIS         rw             rw
--------------------------------
Apache      rw             rw
--------------------------------
Zope        rw             r

The client is always Word 2000 under Windows. So the Zope/Word combinatio=
n
is the only one, which opens a HTM-doc in readonly mode.

I was successful in achieving the same behavior wiht apache and mod-dav, =
by
setting the executable mode on the HTM file. As I described already in an
earlier mail. I recorded the communication and the only difference I coul=
d
find is in the HTTP-response to the GET request:

GET /dav/noxbitset.htm HTTP/1.1
Accept: */*
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)
Host: 10.2.1.1

Server: Apache/1.3.19 (Unix)  (SuSE/Linux) mod_python/2.7.2 Python/2.0
DAV/1.0.2

Accept-Ranges: bytes
Content-Length: 2343
Keep-Alive: timeout=3D15, max=3D99

here the file is open in read-write

next the read-only-case

GET /dav/xbitset.htm HTTP/1.1
Accept: */*
Accept-Encoding: gzip, deflate
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

DAV/1.0.2
Keep-Alive: timeout=3D15, max=3D98
Connection: Keep-Alive
Transfer-Encoding: chunked
Content-Type: text/html

I didn't find the place, where to put in the Etag, so I could test with
Zope, if that is really the problem.
