I don't know if this will make any difference, but I redirect users from index.html to index.php. Here is index.html:
<HTML>
<HEAD>
<META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=ISO-8859-1">
<TITLE>My Site</TITLE>
<SCRIPT LANGUAGE="JavaScript"><!--
function redirect () { setTimeout("go_now()",0000); }
function go_now () {
if (document.images) {
top.location.replace('http://www.mysite.org/index.php');
} else {
top.location.href = 'http://www.mysite.org/index.php';
}
}
file://--></SCRIPT>
</HEAD>
<BODY onLoad="redirect()">
</body>
</html>
