Forum: NGINX Regex for rewrite of subdomains

I want to rewrite subdomains by adding a separate server for subdomains 
as


server {
server_name domain.com
...
}
server {
server_name *.domain.com
}

but how I can I ass a rewrite rule int the second server to process
subdomain requests as

keyword.domain.com/query=some to
domain.com/script.php?query=some&sub=keyword

I'd take a look at using pattern matching in a map
( http://wiki.nginx.org/HttpMapModule ) and redirecting if the default
value isn't found? Maybe not the most effective, but simpler to
maintain...

server {
   server_name *.domain.com;

   if ($http_host ~* (.+)\.domain.com$) {
     set $keyword $1;
   }

   if ($request_uri ~* ^/query=(.+)) {
     return 301 http://domain.com/script.php?query=$1&sub=$keyword;
   }
}

I'm not sure a map would be faster in this case because you don't need a
multitude of patterns.

Oh, NO!

server {
    server_name  ~^(?<KEYWORD>.+)\.domain\.com$;
    return 301 
http://domain.com/script.php?query=$arg_query&sub=...
}

Or if the server may process something expect "query":

server {
    server_name  ~^(?<KEYWORD>.+)\.domain\.com$;

    if ($arg_query) {
        return 301 
http://domain.com/script.php?query=$arg_query&sub=...
    }
    ...
}
