LSCache supports GEOIP. To enable it, the following steps need to be followed:

1. Enable the Geolocation database:
   In the LSWS Web Console: General →General settings:→ Enable IP GeoLocation → Yes
2. Install the GeoIP database (for CentOS users):
   yum install Geoip-data
   or
   yum install GeoIP-GeoLite-data
   
   Also check the installation location
   rpm -ql Geoip-data
   or
   rpm -ql GeoIP-GeoLite-data
   
   It may return the database path as:
   /usr/share/GeoIP/GeoIP.dat
   
   In the LSWS Admin Console, configure the database location: General →General settings:→ IP to GeoLocation DB ( enter the database path ).
3. Install other modules:
   yum install GeoIP GeoIP-devel zlib-devel
4. Enable GeoIP on Apache Conf Config the same way you do in Apache, by placing the following directive:
   GeoIPEnable On
5. Use rewrite rules to control redirects:
   For example, add the following rewrite rules to your .htaccess file:
   

   <IfModule LiteSpeed>
     RewriteEngine on
     RewriteRule .* - [E=Cache-Control:vary=%{ENV:GEOIP_COUNTRY_CODE}]
   </IfModule>

You can add rewrite conditions for more specific rules. For example: Show different content or currencies for UK, EU, US, and the rest of the world.

You can also refer to this Maxmind page for rewrite examples.
