title: (HTTP) Hide page extension in the URL
body: <p>I'm making a web page using my Raspberry PI and Apache. I made the page chat.html.
  To connect to it I have to write in Chrome "<a href="http://192.168.1.39/chat.php" rel="nofollow">http://192.168.1.39/chat.php</a>". How can I hide the '.php'(or anything else) from page URL, so when I connect to "<a href="http://192.168.1.39/chat" rel="nofollow">http://192.168.1.39/chat</a>" directly it doesn't give Error 404?</p>
  
  <p>Thank you in advance.</p>
