content of rel and type attribute for embedding favicon with link element

To embed a favicon on a webpage we use the <link> element. Something like this:

<link rel="What goes here?" type="What开发者_JAVA百科 goes here?" href="/favicon.ico"/>

What value do I put in the rel and type attributes?

http://en.wikipedia.org/wiki/Favicon

<link rel="icon" 
     type="image/png" 
      href="http://example.com/myicon.png">

according to wikipedia the above is not supported by IE

<link rel="shortcut icon" href="http://example.com/myicon.ico" />

this solution seems the best to me: -

favicon.ico located in the web site's root
