geoip_country_code header is deleted when I set another custom header

[MarcPapers]

Thanks Ruslan, obviously at the level(http server) that I was setting the
mobile header, it didn't use to inherit the geoip header because it was set
in a previous level (nginx configuration). I didn't see it. Thanks for your
help. What I did for doing it work properly was adding the geoip at the same
level, resulting like that:

location / {
                proxy_pass http://xx;
                access_log  /var/log/nginx/xx.access.log menosbasico;
                proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code;
                proxy_set_header ismobiletraff $mobile_flag;
        }

Thank you very much!
