Hi,

Documentation says that CONNECTION in one place where it is supported so have a try http://mapserver.org/cgi/runsub.html. Validation may be needed or not, I am not sure how to interpret the documentation but you will notice it soon. Take a habit to use DEBUG 5 and read your errorfile while experimenting.

By the way, you do not read polygons from the remote WMS, you read rasters. Thus TYPE RASTER.
