I have setup a wildcard subdomain server(many subdomains)  
server {  
listen 80;  
server\_name ~(?.\*).localhost;  
…  
…  
}

I want to make the subdomain apart of the query in the backend

when we visit [http://clothes.localhost/](http://clothes.localhost/)  
backend query  
[http://localhost/script.php?sd=clothes](http://localhost/script.php?sd=clothes)

or we visit [http://jackets.localhost/large/blue/](http://jackets.localhost/large/blue/)  
backend query  
[http://localhost/script.php?sd=jackets&size=large&colour=blue](http://localhost/script.php?sd=jackets&size=large&colour=blue)

I have tried for 5 hours now, Modifying rewrite and return as many ways  
possible, Multiple errors such as

rewrite ^ http://$subdomain.localhost/script.php?x=$subdomain permanent;

[http://clothes.localhost/script.php/script.php/script.php/script.php/script.php/script.php/script.php/script.php/?sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&](http://clothes.localhost/script.php/script.php/script.php/script.php/script.php/script.php/script.php/script.php/?sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&sd=clothes?sd=clothes&)  
or  
[http://localhost/localhost/localhost/localhost/localhost](http://localhost/localhost/localhost/localhost/localhost)

etc etc(I have tried many more tweaks but didnt record all as I went  
along)

Thanks in advance for any intention to help or answers given.
