Unfortunately, I am not in a position to test/verify the following. Maybe someone can verify or falsify my suspicion, that feed.php
of DokuWiki lacks the Content-Type
HTTP header since "Kaos"!?
For my old Igor:
$ curl -Is https://example.net/dokuwiki/feed.php | grep -i ^content
content-type: application/xml; charset=utf-8
For dokuwiki.org:
$ curl -Is https://www.dokuwiki.org/feed.php
HTTP/1.1 200 OK
