i would use a javascript to call 2 links or you could adapt the headers to launch the music file
javascript one is:
put this in between the <head> tags
<script language="javascript">
function loadTwo(iframe1URL, iframe2URL) {
parent.tools_f.location.href=iframe1URL
parent.cont_f.location.href=iframe2URL
}
</script>
and the the link like this
<a href="javascript:loadTwo('counter.php?counter=1','http://www.aconeinc.com/sounds/hollademo.m3u')">Click for music</a>
hope that helps,
Hugh
[Forgot to add that i am loading each paqe into a seperate iframe]
