If you don't have access to configure you web server, you can still send the header from a Coldfusion script. It's a case of adding the following to your Coldfusion scripts:
<cfheader name="Access-Control-Allow-Origin" value="*">
var response = getPageContext().getResponse(); response.setHeader("Access-Control-Allow-Origin","*");
Note: This needs to be set before any output has been sent from the server.
