[OpenLayers-Users] NASA Worldwind Layer

[Chris Holmes]

How similar is their caching scheme to openlayers?  I'd really like to 
reach a tiling spec so that the tiles requested are the same, so that 
servers can do caching across different clients: just stick squid in 
front, or create just one set of tiles.
