Certamente. Ecco il codice del file index.html
codice:
 
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
   "http://www.w3.org/TR/html4/loose.dtd">
    <html>
	<head>
		<meta http-equiv="Content-Type" content="text/html;charset=utf-8">
		<title>miosito.com</title>
		<meta name="title" content="miosito.com - descrizione">
		<meta name="description" content="*description*">
		<meta name="keywords" content="*key words*">
		<meta name="robots" content="all">
		<meta name="revisit-after" content="14 days">
	</head>
	<body>
	<script type="text/javascript">
	var width = screen.width;
	var res =(((!(640-width))*1)+((!(800-width))*2)+((!(1024-width))*3)+((!(1152-width))*4)+((!(1280-width))*5)+((!(1600-width))*6));
	if(!(res)) res = 6;
	if (res=='1') {window.location='/alert.xml'}
	if (res=='2') {window.location='/800/800.xml'}
	if (res=='3') {window.location='/1024/1024.xml'}
	if (res=='4') {window.location='/1152/1152.xml'}
	if (res=='5') {window.location='/1280/1280.xml'}
	if (res!='1' && res!='2' && res!='3' && res!='4' && res!='5') {window.location='/larger/larger.html'}
	</script>
	</body>
	</html>
ed ecco il codice di uno dei files .xml che funzionano perfettamente con Opera, Safari, Chrome e Firefox ma non con IE
codice:
