Some files are not gzipped on their way to the user browser in our setup.

for example

http://myhostname.com/css/build/20120904-1.css

http://myhostname.com/js/dojo/dn/main.js?20120904-1

http://myhostname.com/js/jquery-min/compiled.js?20120725-4

can not be zipped.

my current configuration:

        location ~* \.(js|css|png|jpg|jpeg|gif|ico)\.*+$ {
            if ($args ~ [0-9]\.*+) {
               expires max;
               break;
            }
            expires max;
            log_not_found off;
             gzip  on;
    }

What needs to be adjusted to make gzip fly? I already tried several other options but don't want to continue with try&error on this.

Thank you very much.
