I was wondering if it was possible to write some .htaccess page that makes the server use an index.php file in a SINGLE directory as the index file for every directory/sub-directory on my server, rather than placing the exact same index.php in 200+ directories. If my description isn't clear, what I essentially mean is: /files/index.php is to be used as the index for, for example, /files/morefiles, as well as the index for all directories and sub-directories within /files/, even though those directories would not have an index file themselves. Thanks to all in advance.
EDIT: The php file generates different output based on the directory; To be specific, it lists the contents of the current directory if a certain cookie is set. So, unfortunately, URL rewriting won't work.
