Usage:
/etc/hosts:go run main.gohttp://foo.com:8081/in your browser while watching javascript consoleFinished CORS request {"name":"TaskNotFound","message":"task guid not found"}CORSEnabled: falsein main.go, you should seeXMLHttpRequest cannot load http://bar.com:6700/v1/tasks/abcd. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://foo.com:8081' is therefore not allowed access. The response had HTTP status code 401.
