php header redirect IE issue

In web development, a HTTP POST is often processed on the server ending with a header("Location:page.php") call, so that user can refresh their page without re-posting. This usually works well.

The only issue is IE. After posting or file upload, using the PHP header() call won't work with IE, although it works with Firefox. You will have to use the HTML direct instead.
