Hello,

I have two small bits in my configuration that I'm worried about.
One it to redirect users based in their country to a specific page.
The other is to choose the upstream based in a cookie.

'm am worried about performance and would like to know if this small bits are evil to my site.

================================
### Map Member ID Cookie

map $cookie_memberid $prxy {
default upstream-1;
~^[1-9]\d*$ upstream-2;
}
### / Map Member ID Cookie

### Map Country Code
map "$geoip_country_code.$arg_section" $registo {
default 0;
AAA.register 1;
BBB.register 1;
}

map "$geoip_country_code.$arg_serviceClick" $registo {
default 0;
AAA.facebook 1;
BBB.facebook 1;
}
### / Map Country Code

server {

# Main location
location / {

# GeoIP
if ($registo) {
return 301 /pages/registo;
}

proxy_pass http://$prxy;
}
==============================

Thanks
