For a responsive Website I prefer Dynamic Serving, But i don't know how it work the link is here https://developers.google.com/webmasters/mobile-sites/mobile-seo/dynamic-serving
So i fount the solution use GET /page-1 HTTP/1.1 Host: www.example.com (...rest of HTTP request headers...) HTTP/1.1 200 OK Content-Type: text/html Vary: User-Agent Content-Length: 5710 (... rest of HTTP response headers...)
