How do I use URLs without page extensions? For example, MakeUseOf has an Answers ask page which is http://www.makeuseof.com/answers/ask/. Now, this page is actually .php I think, and whenever I try to make my own website I have to use the .php extension to bring up a page. But when I go to the MakeUseOf link, that extension is not needed. How can I make my website do that?
