You can add this in preview now!? How does one go about setting this?
From what I understand, it is a server/host side setting that can be configured into your web service (apache). Basically it means, from your server's point of view, that if a website or program that ISN'T on the same server requests a file, that it is OK to send it.
When you preview, your domain is basically local host, which is a different domain than your web host at http://www.****.com. So your request won't go through by default, unless your web host is specifically configured to allow it.
