[Qgis-user] [QGIS-Server] WFS-T

Tue Feb 5 04:09:35 PST 2019

Hi Berhnard,

Well, on the issue of why QGIS is using WFS 1.0.0 despite asking for 1.1 
- from the docs it appears QGIS Server only supports WFS 1.0.0, so they 
"negotiate" down to that version.

I'm afraid I can't help on your other question; hopefully someone else can.

Cheers,

Jonathan
