Theme based on external WFS

Theme based on external services means that the Adaptive Map Server makes a call to the remote service each time the user panes the map. The map images generated on the service are then sent via Adaptive’s map server and to the user. In order for this to work, it is necessary that the Adaptive Map Server has http access to the service.
