How To Redirect To An External Website Using Webflux endpoints

ServerHttpResponse response;
String google = "www.google.com"
response.setStatusCode(HttpStatus.TEMPORARY_REDIRECT);
response.getHeaders().setLocation(URI.create(google));
return response.setComplete();

I tried the above code it redirects to localhost:8080/www.google.com

How can I get https://www.google.com without localhost part?

Trying with spring webflux

Thanks
