[Qgis-user] WFS - Env variable QGIS_SERVER_API_WFS3_MAX_LIMIT not working

Tue Feb 14 03:15:22 PST 2023

Hi,

that variable is for OAPIF (AKA WFS3) only, it does not apply to plain old WFS.

There is a bug in the manual, I'll fix that.

It should read:

QGIS_SERVER_API_WFS3_MAX_LIMIT

Maximum value for limit in a OAPIF features request.
