I have UMN configured as a cascading mapserver. I want it to reproject the map while cascading through UMN. How can I do that? Is that possible at all?

A:
I think as long as MapServer is configured with GDAL support then setting the projection on a layer will automatically call use this tool to reproject:
http://www.gdal.org/gdalwarp.html
Otherwise it may have to be scripted.
Your layer definition should look similar to below:
http://mapserver.org/ogc/wms_client.html
LAYER
NAME "prov_bound"
TYPE RASTER
STATUS ON
CONNECTION "http://www2.dmsolutions.ca/cgi-bin/mswms_gmap?"
CONNECTIONTYPE WMS
PROJECTION
"init=epsg:42304"
END
METADATA
"wms_srs" "EPSG:42304"
"wms_name" "prov_bound"
"wms_server_version" "1.1.1"
"wms_format" "image/gif"
END
END

Cascading mapserver means, that I define a layer which data comes from a different external WMS. Changing projection in this case is what I'm interested in.

Have you checked the WMS_SRS metadata property of the origin WMS? Sometimes they are set up to support multiple projections - if yes you can pass in the relevant SRS parameter in your URL calls. Does changing the PROJECTION in your WMS layer definition in a map file do anything?
