I know 2 ways of doing a bookmark icon:
  1. You create an icon, rename it to favicon.ico and put it in the directory where your site is.
  2. you add in the head-section of your html a link tag like this:
    <link rel="bookmark icon" href="(X)" />
    where (X) is the link to the icon on your webserver
But my question: Has it ever been standardized, and if so which way to go?
