web国际化方式有很多种，从运维角度，可以在Nginx上做一个，根据求情head携带的语言信息做跳转

Nginx具体配置

server {
        listen       80;
        server_name itttl.com;

        location / {
            set $lang zh_CN;

            if ($http_accept_language ~* ^en)       {
                set $lang en_US;
                rewrite (.*) http://en.itttl.com$1 permanent;
                break;
            }

            rewrite (.*) http://www.itttl.com$1 permanent;
        }

        access_log  /data/log/nginx/access/itttl.com.log;
}

• 其中en.itttl.com为英文站,www.itttl.com为默认的中文站
