Oh, naturally. I was thinking about how to pass on the GetCapabilities info, but with cascading WMS it is me who is generating and sending that info for the clients. And if I remember right, GetFeatureInfo does not work with cascading WMS so it does not matter if Mapserver does not know where to send those requests.
