Different GetCapabilities and GetMap onlineresources in WMS

The latter.  As a WMS Client, MapServer does not parse the remote WMS'
Capabilities XML, but uses the CONNECTION directive within LAYER.  That
said, there are cases (not many, but there are) where OnlineResource's
differ between operations.

So, in this case, you would use the OnlineResource for GetMap as the
CONNECTION in your mapfile.
