I built this plugin to help ease the transition during a DNS changeover, but you can use it any way you please. It turns your WordPress installation into a very simple proxy server. It fetches content from another URL, caches it and displays it. Requests are cached for 24 hours.
Install the plugin, then head over to Settings > Simple Proxy in your WordPress admin. Enter the URL you want to proxy to and when you’re ready to go, also check the enabled checkbox.
You need to have <a href="https://codex.wordpress.org/Using_Permalinks#Choosing_your_permalink_structure" rel="nofollow ugc">pretty permalinks</a> enabled.

Notes
<ul>
<li>Beware: Depending on your map and the tiles you need, a lot of storage is needed.</li>
<li>Might be slower than official servers (depends on your server)</li>
<li>First requests might be slow as map tiles are cached on request</li>
</ul>
Filters
You can use filters to get the URLs from the plugin:
<pre><code> $proxy_cached_url = apply_filters( 'osm_tiles_proxy_get_proxy_url', $proxy_cached_url );
 $proxy_rest_api_url = apply_filters( 'osm_tiles_proxy_get_proxy_rest_url', $proxy_rest_api_url );
 $leadlet_js_url = apply_filters( 'osm_tiles_proxy_get_leaflet_js_url', $leadlet_js_url );
 $leadlet_css_url = apply_filters( 'osm_tiles_proxy_get_leaflet_css_url', $leadlet_css_url );
</code></pre>
Constants
To disable cache invalidation when WP Rocket or WP Fastest Cache invalidate their cache, you can set the following constant in your <code>wp-config.php</code>
<pre><code>define( 'OSM_PROXY_DISABLE_CLEAR_CACHE', true );
</code></pre>
