Hi,  
My nginx location configuration looks like this

```
location ~* ^/z/(\d+)$ {
            set $mID $1;
            set $tag_type 'z';

            access_log /opt/nginx/logs/bright_tag.log

```

bright\_tag\_log;  
if ($arg\_uid ~\* ‘.+’) {  
access\_log /opt/nginx/logs/product\_uid.log  
prod\_log;  
}

```
            if ($arg_orderNumber ~* '.+') {
                    access_log /opt/nginx/logs/conversion.log

```

conv\_log;  
}

```
            if ($arg_prodID ~* '.+') {
                    access_log /opt/nginx/logs/product_uid.log

```

prod\_log;  
}

```
            root html/bright_tag/public;
            passenger_enabled on;
            passenger_set_cgi_param UID $uid_set$uid_got;
    }

```

When I hit the uri /z/123, I am able to access UID parameter in my  
sinatra application. But when I hit this uri /z/123?prodID=25, Nginx  
does not pass UID parameter to my application. I googled around for a  
while about this issue but everything was in vain. Can anyone give some  
suggestions regarding this?

Thanks,  
Dhaval.
