Thank you Merlin.

I almost know all the wiki, including -d and try_files.

Here is what I need to do :

 1. try to server /poipoi/foobar
 2. if the file doesn't exist, check if /poipoi/ exist
 3. if this directory doesn't exist, return a redirect, otherwise return 404

How can I get the base directory of $request_filename ?
