I am planning to use the WMS and WFS Cascading functionalities of Geoserver in order to get some layers from other Geoserver instance. I understand, that using the Cascading requires of creating store/workspace in my Geoserver.
And I can see these (workspace/store/layer) created also in the geoserver/data directory.
I have a basic architecture question: Are these layers copied from the remote Geoserver to my data directory of my local geoserver? Or what I see is just a shortcut to the remote geoserver?
