If your website or app requires a Cross-Domain Policy file to correctly serve your images across domains, you can enable it in the Dashboard by clicking the check box under Security settings:
When enabled, imgix will serve the following file to any client that requests it.
<?xml version="1.0"?>
<!DOCTYPE cross-domain-policy SYSTEM "http://www.adobe.com/xml/dtds/cross-domain-policy.dtd">
<cross-domain-policy>
<site-control permitted-cross-domain-policies="all" />
<allow-access-from domain="*" secure="false"/>
</cross-domain-policy>
