Re: [mapserver-users] Mapserver URL request layer
Hello Sander, 1. Had issues with 4326 to 3301 transformation,the extent and all that. (OpenLayers could manage but QGIS couldnt). Previously only had ows_extent. Is ows_extent even a thing? This only shows wms_extent https://mapserver.org/ogc/wms_server.html#layer-object-metadata Should you use wfs_extent and wms_extent instead? the wms_ / wfs_ / ows_ / oga_ (coming in MapServer 8) Metadata-entry are aiming on your output. So, if you only want to serve wms, you only need the wms_*. wfs_* conigures your WFS-server. If you want to serv wms and wfs and the parameters are the same, you can use ows_ instead. 1. My layer is doing an OGR connection directly to the API URL. Works fine. My question is, the API renews itself every 2 minutes (new data). How does Mapserver handle the request with that connection? I move the map (openlayers), there's a new Mapserver request - does Mapserver make a new request to the API endpoint and get a new json? Or is there some sort of cache? No cache by default. MapServer requests the data source every time mapserver gets itself a getmap or get feature info request (or getfeature when serving wfs). So your WMS serves the actual data any time. If you want a cache, you have to configure mapcache or mapproxy separately. 1. Am I missing something else from the Metadata that I should consider?

Re: [mapserver-users] Mapserver URL request layer
Hi, About ows_* from https://www.mapserver.org/ogc/wms_server.html (Note that each of the metadata below can also be referred to as ‘ows_*’ instead of ‘wms_*’. MapServer tries the ‘wms_*’ metadata first, and if not found it tries the corresponding ‘ows_*’ name. Using this reduces the amount of duplication in mapfiles that support multiple OGC interfaces since “ows_*” metadata can be used almost everywhere for common metadata items shared by multiple OGC interfaces.) -Jukka Rahkonen- Lähettäjä: MapServer-users Puolesta Sander Pukk Lähetetty: keskiviikko 9. helmikuuta 2022 11.26 Vastaanottaja: Jason Snyder Aihe: [mapserver-users] Mapserver URL request layer Hi there!

[mapserver-users] Mapserver URL request layer
Hi there! Trying to use a geojson output from API directly in Mapserver layer. Geojson is per standard, 4326, but my Mapserver and OL (the client) is configured to 3301.
