How to add CORS headers?

[ghost]

Just in the early learning stages with Counterfact. How do I output CORS headers? Ideally I'd like them with every request so I'm not sure if there is a global area to emit headers, but for now I'm just trying this on a single request and I'm not seeing my header come back:

    return $.response[200]
        .header('Access-Control-Allow-Origin', 'http://localhost:9000')
        .random();

This has been taken care of in a recent release. Default CORS handling is now part of the server. It will automatically reflect back the settings from the request header such as the origin and the requested allowed access headers.
