[MapServer-users] WFS, OpenLayers and OUTPUTFORMAT explanations

[mathias cunault]

Thanks,
After some tests and internet searchs, as soon as NAME is set to geojson, I
can use either # MIMETYPE "application/json;subtype=geojson" or
MIMETYPE "geojson" or MIMETYPE "application/geo+json". The thing to avoid
is NAME application/json.

Cordialement,
