The Map Proxy

The plugin comes with a proxy mechanism for map tiles. If enabled the Browser will load the tiles from your server rather than directly from the tile provider.

Use the proxy to hide sensitive credentials in the tile URL or for compliance with local privacy regulations like the European GDPR.

To activate the proxy for each Plugin provisder individually go to the plugin settings and check "Enable Proxy".

Enable proxy mode globally by hooking into the filter acf_osm_force_proxy.

add_filter( 'acf_osm_force_proxy', '__return_true');

The proxy server lives in wp-content/maps/ and is no more than a .htaccessand a small PHP file. The configuration is saved in wp-content/uploads/acf-osm-proxy-config.php and is updated every time the settings are saved.
