coret / map-proxy.php
Created October 16, 2025 11:15
Dit PHP-bestand fungeert als een proxy en cache voor kaart-(tile)afbeeldingen van een beperkt aantal toegestane bronnen. Het doel is om kaarten van externe WMS- of tile-servers lokaal op te slaan, zodat latere verzoeken sneller geladen worden en de externe servers minder worden belast.
<?php
define('SECONDS_TO_CACHE', 30 /* dagen */ * 24 /* uur */ * 3600 /* seconden */);
define('CACHE_DIRECTORY', '****' ); // deze directory moet bestaan op het bestandssysteem
# Beperk het aantal domeinen die via deze proxy opgevraagd en gecachet mogen worden:
$toegestaneDomeinen = [
"https://mapwarper.net/" => "mapwarper.net",
"https://gis.gouda.nl/" => "gis.gouda.nl",
"https://geo.rug.nl/" => "geo.rug.nl"
