I was trying to add a favicon to a website earlier and looked for a better way to implement this than to dump a favicon.ico
file in the root of the website.
Well, the file is in the root so it does not show whether the tag works or if the browser just got the icon from the usual location (the root).
Edit: I'll try it and see if it works.
Edit 2: Using both tags make it work even for any file name as long as the file is an icon for IE7: I tried using .png
files and it only worked with Firefox.
