Yes, that is right. Files in other folders, also if the names of the files end on php5, should not be rewritten.

I am currently on the way understanding what you are doing here. Pretty sophisticated and way shorter than what I would have tried. In my tests this is working as expected. Thanks for the input! :-)

What do you mean? The "main folder", which you are influencing with your first rule, is the web root: /home/$username/www/. The foder wiki is the subfolder in there. Any recommendation what location I should add around the two rewrites or if I should add one?

Cheers!
