When a variable value is not found, it's logged as "-", that's expected behaviour.

This doesn't apply to found but empty values as in your example though. -- Maxim Dounin http://mdounin.ru/ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
