Flash Files with CDN

Note that .swf files might not work properly when stored on CDN because Flash files check the domain where they were loaded from.

To resolve this, create the crossdomain.xml file at origin source and add the following lines into it.

<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
    <allow-access-from domain="*"/>
</cross-domain-policy>

For more details refer to Cross-domain policy for Flash.
