So lets say you find yourself in a situation where you need to keep the files that contain these other languages on a external server (ie. the flash file is on one server, the XML file is on another server, and your images that are being indexed by the XML file are on yet another server). One example of this is a published Advertisement or flash application on the clients server (of which you have no access), that you would like to update on the fly with no access to their server.
In comes crossdomain.xml:
This is it. Host this on the external server in the same directory as the XML file that is being accessed. This gives permission for flash to pull files from a external server. NOTE: the above code give COMPLETE access, and could pose a security risk, this is defined here:
You can specify specific directories where the "*" is, such as:
Popular sites such as yelp, and flickr have a completely open crossdomain.xml file, an interesting article on the security issues posed by this is here:
