<p>Somewhat counter-intuitively, you can use "<span lang="EN-US"><a href="https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600">https://api.digitransit.fi/routing/v1/routers/hsl/isochrone?fromPlace=60.168,24.938&mode=WALK,TRANSIT&date=2019-11-01&time=08:00:00&maxWalkDistance=500&cutoffSec=1800&cutoffSec=3600</a>"
as a filename when using the File source type. This is due to GeoJSON driver having a particular logic when passed a http[s]:// filename to ingest it fully in memory.</span><o:p></o:p></p>
