How can I add a head e.g.

Access-Control-Allow-Origin: [http://www.somesite.com](http://www.somesite.com)

to the response that is sent by the Webdev module?

Thank you, Jonathon. And, I wanted to find some button to press indicating that this answered my question. But, couldn’t find one. Hopefully I haven’t missed one.
