Should you use wfs_extent and wms_extent instead?<br>

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_*.</div>
<div>wfs_* conigures your WFS-server. If you
want to serv wms and wfs and the parameters are the same, you can
use ows_ instead.<br>
<blockquote type="cite">
<ol>
<li>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).<br>
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?<br>
Or is there some sort of cache?</li>
</ol>
</blockquote>
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.<br>

<div>Trying to use a geojson output from API directly in
