There are a few ways.
1)
<script language="javascript">
<!--
window.location = '
http://some.other.page';
// -->
</script>
But that requires javascript.
2)
Put this between the <head> and </head> tags:
<meta http-equiv="REFRESH" URL="
http://some.other.page/" CONTENT="1">
But that will wait 1 second before redirecting.
3)
Or you could try this way (I haven't tested it, but I think it should work):
<meta http-equiv="Location" content="
http://some.other.page/">;
