Hello.

With CloudFront, you can use edge functions such as Lambda@Edge to select the origin based on the request header.

In nginx,I can config like this:

server { location / { root /data/apps/web/www/cf/d;

    if ( $http_user_agent ~ "(MIDP)|(WAP)|(UP.Browser)|(Smartphone)|(Obigo)|(Mobile)|(AU.Browser)|(wxd.Mms)|(WxdB.Browser)|(CLDC)|(UP.Link)|(KM.Browser)|(UCWEB)|(SEMC-Browser)|(Mini)|(Symbian)|(Palm)|(Nokia)|(Panasonic)|(MOT-)|(SonyEricsson)|(NEC-)|(Alcatel)|(Ericsson)|(BENQ)|(BenQ)|(Amoisonic)|(Amoi-)|(Capitel)|(PHILIPS)|(SAMSUNG)|(Lenovo)|(Mitsu)|(Motorola)|(SHARP)|(WAPPER)|(LG-)|(LG/)|(EG900)|(CECT)|(Compal)|(kejian)|(Bird)|(BIRD)|(G900/V1.0)|(Arima)|(CTL)|(TDG)|(Daxian)|(DAXIAN)|(DBTEL)|(Eastcom)|(EASTCOM)|(PANTECH)|(Dopod)|(Haier)|(HAIER)|(KONKA)|(KEJIAN)|(LENOVO)|(Soutec)|(SOUTEC)|(SAGEM)|(SEC-)|(SED-)|(EMOL-)|(INNO55)|(ZTE)|(iPhone)|(Android)|(Windows CE)|(Wget)|(Java)|(curl)|(Opera)" )
            {
                    root /data/apps/web/www/cf/m;
            }
    error_page  403 404 500 502 503 504  /index.html;
}

}
