[mapserver-users] Problem using WMS GetFeatureInfo in OpenLayers with different projections

[Rahkonen Jukka (Tike)]

Hi,

Please show us the complete GetFeatureInfo requests for both cases. Server urls are not interesting but all the WMS parameters. Have you already tried to send them from browser? Testing with OpenLayers is waste of time because you can't control what really happens but with hand written requests you are the master.
