		console.log(line);
		handleResponse(JSON.parse(line));
	}
}, false);

#Use in Angular JS

const EventSource: any = window['EventSource'];
    const es = new EventSource('http://10.1.16.61:8080/SpringMVCHibernateWithSpringSecurity/register/${uuid}',
      { headers: { 'Content-Type': 'text/event-stream' } });
    es.onconnect = (e) => {
      console.log(e);
    }
    es.onmessage = evt => {
      console.log('Event source testing', evt);
      const data = JSON.parse(evt.data); // TODO handle parse error
    };
