Regex for rewrite of subdomains

Server NGINX
1

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
( Module ngx_http_map_module ) and redirecting if the default
value isn’t found? Maybe not the most effective, but simpler to
maintain…

}
}

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

Or if the server may process something expect “query”:

server {
server_name ~^(?.+).domain.com$;

if ($arg_query) {
    return 301

http://domain.com/script.php?query=$arg_query&sub=$keyword;
}
…
}
