When I ask the server for an URL which has no extension, but is not a directory, apache automatically adds a .php extension to it. Where is this behavior configured?
EDIT: I'm sorry, my question wasn't clear: I'm not asking how to do this, I just found out that my local server (Apache/2.2.11 on Debian) does it by itself (i.e. I have no rewrite rules) and I wanted to know where this can be configured.
