Is it possible to toggle visibility of a map service based on scale dependency that is not a tiled or bing service? I see this entry in the help:
<LI value=5>displaylevels - To specify which scale levels this layer should be displayed at. Only applies to "tiled" and "bing" layers.
For my own dynamic map services, I can adjust layer visibility through scale dependency in ArcMap. However for WMS or other AGS that I am sourcing from external sources (I have no control), how can I set the visibility scale of this, without having first to add it to an ArcMap and republish as my own service?
