... schon mal gegoogelt? meta refresh target:
"Problem: A meta refresh tag can't target a frame other than the current.
Workaround: Use a JavaScript timed location change.
Code Example: We have a frame named right. The delay is 3 seconds.
<script>
setTimeout("top.right.location = 'p.html'", 3000);
</script>
Note: Remember that top is a reserved word. So use names like upper and lower instead of top and bottom."
remember: dont post twice...
