Cross-Origin Resource Sharing (CORS) allows JavaScript code running in a browser on an external host to interact with your mobile service. Specify the origins that should be allowed to make cross-origin calls (for example:  http://example.com:12345). Use "*" to allow all.

These settings affect only the use of your mobile service from web applications. Native applications can access your mobile service regardless of CORS settings.
