A lightweight RESTful geospatial feature server based on DuckDB - tobilg/duckdb_featureserv

I wan't to use the pg_featureserv service to deliver data from a PostgreSQL/PostGIS database to be displayed in Openlayers. The displayed maps are for internal use only, so the maps are only accessible when users are logged in. Actually anybody calling the url of the pg_featureserv service directly http://map.mydomain.com:9000/collections/schema.areas/items.json has access to the data. I wan't to restrict this, so that only the map-pages from the server (the same where the PostgreSQL/PostGIS and the pg_featureserv are runing on) have access to the data. But when I change the HttpHost settings to 127.0.0.1 or to the IP adress of our server, the data isn't displayed anymore in the Openlayers map. The pg_featureserv.toml looks like this: [Server] # Accept connections on this subnet (default accepts on all) # HttpHost = "0.0.0.0" # HttpHost = "127.0.0.1" HttpPort = 9000 UrlBase = "127.0.0.1:9000" The requested data is displayed fine inside the Openlayers map. var areas = new ol.layer.Vector({ source: new ol.source.Vector({ url: "http://map.mydomain.com:9000/collections/schema.areas/items", format: new ol.format.GeoJSON() }) }); var map = new ol.Map({ target: 'map', layers: [ new ol.layer.Tile({ source: new ol.source.OSM() }),areas ], view: new ol.View({ center: ol.proj.fromLonLat([6.2, 49.6]), zoom: 12 }) });

If one is to use pg_featureserv from Crunchy Data for displaying features on a webmap, what would be the best way to perform crud operations? Is it at all possible to update info?
