Geo Targeting / GeoIP
Altis supports geolocation targeting when specifically enabled. Once enabled, developers can make use of the
Cloudfront-Viewer-Country HTTP Header (ISO 3166-1 alpha-2 format) to serve content on a per-country basis.
To enable Geo Targeting contact the Altis team.
When Geo Targeting is enabled, all page caches will be stored per country. Depending on the shape of traffic, this can reduce cache hit rates considerably.
The following is an example to show posts to a user that have a tag matching the viewer's country:
$posts = new WP_Query( [ 'tag' => sanitize_text_field( $_SERVER['HTTP_CLOUDFRONT_VIEWER_COUNTRY'] ), ] );
