title: FIle download even when extension is not entered
body: <p>In apache, I can do something very strange. Imagine I have a folder named 'dir' and that inside it there there is the file '123.zip'. If i get to a browser and write in the URL bar 'http://mydomain.com/dir/123.zip' I download the file as it is suposed to happen, but if I type 'http://mydomain.com/dir/123' instead, I download the file as well. Is this suposed to happen? If so, is there any way to deactivate it?</p>
