Lets say I have a plain text file example.txt and I have a PHP script on my web-server readfile.php.
What I want to be able to do is to prevent users from typing http://www.example.com/example.txt and looking at the text file directly but I still want people to be able to load http://www.example.com/readfile.php which reads from the file example.txt and does something with it (possibly displays the contents of the file).
Also, if this can be done, what is the best way to do it?
