wp_favicon_request function

[dugi digitaly]

wp_favicon_request function not work if wordpress installed on directory like www.domain.com/wp/
$_SERVERREQUEST_URI is wp/favicon.ico

// www.domain.com/wp/
// $_SERVER['REQUEST_URI'] is 'wp/favicon.ico' <--
function wp_favicon_request() {
	if ( '/favicon.ico' == $_SERVER['REQUEST_URI'] ) {
		header('Content-Type: image/vnd.microsoft.icon');
		header('Content-Length: 0');
		exit;
	}
}

my alternative is

if ( substr($_SERVER['REQUEST_URI'], -11 ) == 'favicon.ico' )

Good catch! Maybe we should take home_url into account here.
