[MapServer-dev] MapServer WMS client CRS:84 support

[Seth G]

Hi Tamas,

Having gone through the projection code recently I doubt this format is supported. Could you use PROJECTION "epsg:4326 END on the layer and then hard code the projection string?

CONNECTIONTYPE WMS
CONNECTION "https://demo.org/cgi-bin/wms?VERSION=1.1.0&LAYERS=bm&FORMAT=image/png&SRS=CRS:84"
