Here ya go:
<!--index.html-->
<html>
<head>
<script LANGUAGE="JavaScript">

<!--cloak engaged

function SetCookie (name, value) {
var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) +
((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");
}
function set_loaded(value) {
var expdate = new Date ();
expdate.setTime (expdate.getTime() + (48 * 60 * 60 * 1000 * 31));
var cookievalue = value
SetCookie ("beenhere", cookievalue, expdate);
}

function docookiecheck(){

if (document.cookie.indexOf("beenhere") == -1) {
set_loaded('true');
}
else {
location.href="index2.html"
}
}

// End -->
</script>
</head>
<body bgcolor="#FFFFFF" marginwidth="0" marginheight="0" leftmargin="0"
topmargin="0" onload="docookiecheck()">
<!-- rest of main content -->
</body></html>

Just move the function call to docookiecheck() to wherever you like.  Using
it in onload will mean that they will still see the entire contents of
index.html (however briefly) before being redirected to index2.html.
Alternatively you could do something like:

<body bgcolor="#FFFFFF" marginwidth="0" marginheight="0" leftmargin="0"
topmargin="0">
<script LANGUAGE="JavaScript">

docookiecheck();

</script>
<!-- rest of main content -->
</body></html>

...which would call it immediately - instead of waiting for the page to
load.

Of course I havent tested this out, but it seems sound.
