Geo blocking, but allowing google index robot to pass-thru

unknown · February 18, 2013, 1:01pm

Hi

I have a site where i want to geo block all but one country, but perhaps
allow Google to index site, perhaps some other index bot too.

So what sort of configuration is needed so i can detect Google bot and
let
it pass-thru? Would be nice if there is example configuration. Is only
good way to check user-agent?

Here’s some code I use for a similar setup…

map $geoip_country_code $external_redirects {
default ‘Block’;

US http://www.example.com;
}

#Whitelist crawlers
map $http_user_agent $crawler {
default 0;

~*(AdsBot-Google|Googlebot-Mobile|Googlebot-Image|Mediapartners-Google|
bingbot|Feedfetcher-Google|Googlebot|Yahoo\ !Slurp|msnbot|msnbot-media|
YahooCacheSystem) 1;
}

You’ll also probably need to override for specific IP addresses too…

geo $whitelisted {
default $crawler;

localhost

127.0.0.0/8 1;

CloudFlare

204.93.240.0/24 1;
204.93.177.0/24 1;
199.27.128.0/21 1;
173.245.48.0/20 1;
103.21.244.0/22 1;
103.22.200.0/22 1;
103.31.4.0/22 1;
141.101.64.0/18 1;
108.162.192.0/18 1;
190.93.240.0/20 1;
188.114.96.0/20 1;
197.234.240.0/22 1;
198.41.128.0/17 1;
}

You can then use your own logic with the values of $external_redirects
and $whitelisted to control redirections.

hth,
