[Users] How to change projection of a baselayer...

[Hugo]

Hi Kai,

I think you have to define the spherical mercator projection of your
baselayers in their correspondent mapfile because WMS cannot be reprojected
on the client side.

You would add soething similar to the following in your mapfile:

PROJECTION
  "init=epsg:900913"
 END

Hope this helps.
Cheers,

Hugo
