Nginx从变量或任何字符串中提取值

Question

有没有使用If从Nginx配置文件中的变量中提取值的替代方法？

即

    if ($http_referer ~* (?<=url=)([\w-.]*)(?=/) ){
            set $proxied $1;
            rewrite (?<=/)(.+\.(css|jpg|png|gif|js)) http://$proxied/$1 redirect;

     }

谢谢

是.http://nginx.org/r/map

map $http_referer $proxied {
    default  example.com;
    "~*(?<=url=)(?<p>[\w-.]*)(?=/)" $p;
}
