FWIW, I still find the "error message" kinda confusing: HTTP/200 for GET,
but HTTP/404 for POST, I didn't know where to go from here. But, strace(1)
was able to shed some light:
$ sudo strace -tt --decode-pids=comm -s1024 -f -o /tmp/foo \
-p $(echo $(pgrep php) $(pgrep apache) | sed 's/ /,/g')
I did not know wether Apache or PHP-FPM was actually triggering the
HTTP/404 so I straced both process groups. And there it was:

But /var/www/wiki does not exist, only /var/www/mediawiki does, so in the
end that ticked me off that all this was caused by that ShortURL hackery.
Oh well, it works now :-)
