thanks a lot for this post. i am working on a cms and these headers were a headache. i had been trying a way around since yesterday (Oct. 25, 2009). i followed your directions on ob_start(() and ob_end_flush(), and my headers are not a headache anymore.

e.g.

<script type="text/javascript">
function redirect(loc){
window.location = loc;
}
</javascript>
 
<script type="text/javascript>redirect("http://www.mindwiremedia.net");</script>
<meta http-equiv="REFRESH" content="0;url=http://www.mindwiremedia.net">

The javascript redirect seems to act quicker to request the url compared to the HTML redirect even if set at 0. This is why it is underneath the javascript and again encase the user does not have javascript enabled.
