I’m running a test sandbox locally. Anyone know an easy way to make my sandbox RPC service add a
Access-Control-Allow-Origin: * header so that I can avoid CORS errors while testing locally?
rpc.tzbeta.net seems to add the header, so I can access it from my web app just fine, but it isn’t currently running the latest proposal code, so I can’t use it for testing.
One option for testing would be a proxy, but if there is a way to tell the RPC service to do it for me, that would be ideal.
