Access-Control-Allow-Origin header missing?

[r***@charter.net]

I have the following code to add the appropriate header then redirect
but I am still getting an error that this header is missing. What am I
doing wrong?

header("HTTP/1.1 301 Moved Permanently");
header("Access-Control-Allow-Origin:
http://".$_SERVER['HTTP_HOST']);
$augmentedUrl = $playbackbase."?authTicket=$authTicket";
header("Location: $augmentedUrl");

Thank you.

HTTP_HOST always has origin access to resources afaik (unless you are using
subdomains that is), just confirm that it is the host you want to give
access to. Besides that I think you want to have that access control @
$playbackbase url as well.
