- Adding the HTTP header "Accept: */*" made sure all read actions ( e.g.
GET, PROPFIND, REPORT) worked perfectly
This is interesting. The Accept header has to do with what media types
the browser will accept in return. I didn't think it had anything to
do with what operations the server/application accepts. Must go read
further....
I'll have to revoke this statement, as I can't reproduce it anymore.
I noticed the DaviCal didn't use it, bu the CURL call did - and yielded
more ( = meaningfull) results.
But, as I said, can't reproduce it.
The thing I could reproduce was that, if the request was sent to the
default port, AND this port was included in the "Host" header, both GET
and PUT yielded HTTP 404.
Only problem remaining was that PUT still isn't possible - at least not with
one of the providers. Since I used a verbatim copy of a PUT action from the
RFC, I strongly suspect the problem to be with the provider.
You've no doubt considered this already, but it might be intentional
on the provider's part. I'm not up on all the webDAV/calDAV providers;
I imagine some of them might add in additional layers of auth
(including the NOWAI layer) just to consider themselves more secure.
Yes I did, but the following arguments should negate that consideration:
- when running OPTIONS, PUT is included in the allowed HTTP methods
- the HTTP return code from the PUT command is 301, where a security
issue would have yielded a code in the 400 range
- I think the CalDAV spec does mention Basic auhentication, so it can't
be anything more sophisticated
- the other provider does respond as expected (though I agree, that is
the weakest argument: expectations != specifications )
- the provider does allow sync'ing Sunbird, iCal, ... over CalDAV, and
that works, even entering a new event (which is a PUT action). The
Charles debugging proxy too shows that it's only Basic authentication
that's going up - and succeeding
I'll add the code I used for the tests.
When looking for the configuration ( Calendar URL, ...), the search term
"CalDAV <provider> Calendar Sunbird" always did the trick for me.
( I also had to modify the Davical client class a bit - make some
protected members public for this test code to work)
