Description Thiago Macieira 2005-01-29 05:12:45 UTC 
Version:           desconhecido (using KDE 3.3.91 (beta1), compiled sources)
Compiler:          gcc version 3.4.3
OS:                Linux (i686) release 2.6.9

This test has been done on a local WebDAV server, with Apache. The only difference between either test, is the presence or the absence of the configuration:

	SetOutputFilter DEFLATE

The request is:

The answer WITH the directive was:

kio_http: (11558) --empty--

WITHOUT it, the answer was:
kio_http: (11559) ============ Received Response:
kio_http: (11559) "HTTP/1.1 207 Multi-Status"
kio_http: (11559) "Date: Sat, 29 Jan 2005 04:09:10 GMT"

kio_http: (11559) "Content-Type: text/xml; charset="utf-8""
kio_http: (11559) --empty--

The difference is the Vary: and Content-Encoding: lines.

The end result is that Konqueror displays an error saying the path doesn't exist.
Comment 1 Waldo Bastian 2005-02-17 17:13:51 UTC 
Does it work with other dav clients? 
I can't reproduce here because I don't have apache 2 installed here and I can't find mod_deflate rpms for apache 1.3
Can you make your webserver accessible?
Comment 2 Thiago Macieira 2005-02-18 05:05:07 UTC 
That was a Subversion repository. And libneon (Subversion's HTTP client library) works fine with it.

I can make my server available if necessary.
Comment 3 Thiago Macieira 2005-02-18 05:13:34 UTC 
I should mention that GETs (answer 200) work. It's just PROPFIND (answer 207) that is mishandled. I'm not sure about other requests/replies.
Comment 4 Thiago Macieira 2005-02-18 12:21:47 UTC 
Maybe related, maybe not: after I logged in to wiki.kde.org, the webpages started showing garbage. They are transferred gzipped. No DAV is involved.
