Nginx提取一個變量或任何字符串的值

Question

是否有替代方法使用If從Nginx配置文件中的變量中提取值？

即

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

    } 

感謝

是。 http://nginx.org/r/map

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