Hello everybody.
I have a nginx (version: nginx/0.7.67) running as a loadbalancer for two
tomcat7 servers with the geoip module. It was working correctly until I
changed the configuration file placed in available-locations called
default
(we work only with the default one). The changes were made to detect
mobile
traffic and include a custom header. Changes are shown below:
BEGIN DEFAULT
#—>content added after “server{”
server {
set $mobile_flag NO;
regex for determining if it is mobile traffic
if ($http_user_agent ~*

END DEFAULT FILE
The proxy_set_header directive for geoip is placed in nginx.conf
BEGIN NGINX.CONF
…
…
http {
access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
rewrite_log on;
proxy_set_header X-Forwarded-For $remote_addr;
geoip_country /usr/share/GeoIP/GeoIP.dat;
proxy_set_header GEOIP_COUNTRY_CODE $geoip_country_code;
…
…
END NGINX.CONF
The problem is that now, the ismobiletraffic header is set correctly,
but
the geoip headers have disspeared from the request. Seems to have been
overwritten. Should I place the mobile traffic detection on NGINX.CONF
at
http{ } level? I have been looking for a solution but I didn’t find
anything
helpful. Thanks in advance for your tips and advices!
Thanks,
Marcos.
