title: How do I disable or redirect a php page unless its hot-linked?
body: <p>I have a page called club.php. I want to disable people from being able to see my webpage if they type in www.mysite.com/club.php unless they are linked from another page. I have a page where you need to enter a password to access this.</p>
  
  <p>I'm hoping I can simply drop code into my pages (javascript or something?)</p>
