With Apache 2.2 I get the error Cannot map GET /folders/kd732205070/s%F6nder%DFeich%E4n/index.html HTTP/1.1 to file. The same URL works with Apache 1.3 Is there a config Option to make it work again with Apache 2.2
Filenames in Apache 2.2 on (winnt, specifically, but also others such as mac) are actually utf-8 formatted. It's the only mechanism which allows you to serve every file name that can be saved on NTFS filesystems.
