I've got a response, and it might be easier than I thought it would be.

We need to add the following line to the response header at
hydra.gnu.org:

  Access-Control-Allow-Origin: "http://www.gnu.org";

Here's how to do it:
  http://enable-cors.org/server_nginx.html

Which boils down to adding this line to the nginx config:
  add_header 'Access-Control-Allow-Origin' 'http://www.gnu.org';

Kind regards,
Roel
