Mapserver handling BBox in different coordinate systems

[Barend Köbben]

Dag Milo,
 
I think you just need two different mapfiles, one for the WGS84 extent and one for the RD one. No need to copy the mapserver executable. 
 
Or better, just have one mapfile allowing both EPSG's and call mapserver using WMS requests (better anyway, why not do it the OGC interoperable way?). That way, you specify the EPSG & BBOX in the request...

I know, but if the BBOX gets set when zooming in and the BBOX
coordinates are outside the RD Stelsel coordinate system it returns a
blank map.
