Cross domain policy in flash

Cross domain data Transfer.

When a Flash document attempts to access data from another domain, Flash Player automatically attempts to load a policy file from that domain. If the domain of the Flash document that is attempting to access the data is included in the policy file, the data is automatically accessible.

Policy files must be named crossdomain.xml, and can reside either at the root directory or in another directory on the server that is serving the data. Policy files function only on servers that communicate over HTTP, HTTPS, or FTP. The policy file is specific to the port and protocol of the server where it resides.

The sample policy file is given below

<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="www.yourdomain.com" /> // Allow the yourdomain domain
<allow-access-from domain="105.216.0.40" /> // Allow domain with the IP Address
<allow-access-from domain="*.something.com" /> //Allow doamins which ends with something.com
</cross-domain-policy>
