A while ago I upgraded Apache running on my Windows machine from 2.2 to 2.4 (2.4.9 to be exact). I did so by installing the WampServer stack. Some things stopped working and I was able to fix most of them but one. My WebDAV setup stopped working after the migration. Since I rarely use it I let it be but today I decided to dig into it and have found the problem to be a bug in Apache 2.4.x (could be other versions too).
