CORS Limitations

If the client is a browser, there is a known issue with this plugin caused by a limitation of the CORS specification that prevents specifying a custom Host header in a preflight OPTIONS request.

Because of this limitation, this plugin only works for Routes that have been configured with a paths setting. The CORS plugin does not work for Routes that are being resolved using a custom DNS (the hosts property).

To learn how to configure paths for a Route, read the Proxy Reference.
