-## crossdomain.xml
-
-The _cross-domain policy file_ is an XML document that gives a web client —
-such as Adobe Flash Player, Adobe Reader, etc. — permission to handle data
-across multiple domains, by:
-
- * granting read access to data
- * permitting the client to include custom headers in cross-domain requests
- * granting permissions for socket-based connections
-
-__e.g.__ If a client hosts content from a particular source domain and that
-content makes requests directed towards a domain other than its own, the remote
-domain would need to host a cross-domain policy file in order to grant access
-to the source domain and allow the client to continue with the transaction.

-specification](https://www.adobe.com/devnet/articles/crossdomain_policy_file_spec.html).
