title: How to set default icon for each page for my website
body: <p>I have seen some servers have default page icon for each pages without having to add using html.
  example:</p>
  
  <blockquote>
    <p><a href="http://facebook.com" rel="nofollow">http://facebook.com</a></p>
    
    <p><a href="http://google.com" rel="nofollow">http://google.com</a></p>
  </blockquote>
  
  <p>and even
  the site in which we are i.e </p>
  
  <blockquote>
    <p><a href="http://stackoverflow.com">http://stackoverflow.com</a></p>
  </blockquote>
