I don't think I understand. The favicon HTML is returned as part of the
page served after going through the PHP engine yes? If you could determine
which types the browser supported at that stage then you could surely echo
back the relevant HTML? I'm thinking now, as it's a <LINK REL="icon" />
that there would then be *another* HTTP request to the web server in order
to retrieve the icon, but that this wouldn't come through the PHP engine and
so there's still no way you can determine what it would be accepting.
Now I'm wondering if I can force it through the PHP engine...
<link rel="shortcut icon" href=http://www.example.com/favicon.php />
This is really distracting!!!!
