You can use a HTML page with no need to any script. Below is an example:
<HTML>
<HEAD>
<META HTTP-EQUIV="Refresh" content="10; URL=/mypage.html">
<TITLE>Redirection...</TITLE>
</HEAD>
<BODY>
<CENTER>You will be redirected after 10 seconds to my <A HREF="/mypage.html">great page</A>.</CENTER>
</BODY>
</HTML>
