Serving apple-touch-icon from root
When you don’t specify any icons in your html with <link rel="shortcut icon" ...>
, Safari on iPad 4 will first try:
apple-touch-icon-144x144-precomposed.png
apple-touch-icon-144x144.png
apple-touch-icon-precomposed.png
apple-touch-icon.png
In that order from the root of your server. It will ignore apple-touch-icon-57x57-precomposed.png or any other files with sizes specified other than 144 (thats 144 not 114 ;).
