Mapserver extent and projection

[Vincent Da-Col]

Hello,

I'm really new to the world of mapserver. I work on it since 2 week. I like
working on this great programme, but I have a little probleme with the extent
and different projections.

I have 2 layers:

- one in Lambert II projection (EXTENT  -760555 -1058700 4505870 3245049)
- the other in WGS84 projection (EXTENT -34.5523788 26.2114230 72.2516881
83.340374)

So How could I dislay the two layers together in mapserver?

Must I reproject one layer in arcgis, or is it possible directly with mapserver?

Thank for the help,

Vincent Da-Col
