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
