Add Access-Control-Allow-Origin header to LocalServer module responses

[cbh6]

Hi,
Is it possible to add Access-Control-Allow-Origin header to localServer responses ?

I'm trying to load images and videos from file system and take snapshots from them with html2canvas
https://github.com/niklasvh/html2canvas. But since files are served from localServer, I need them to be served with res.setHeader("Access-Control-Allow-Origin", "*");

Thanks in advance.
