When ask server1 for data 0,0,40,40, data inside 0,0,20,20 will be served normally, and data outside wil be returned as null. BTW, we have almost 40+ wmts servers which server data at different TileMatrix or different extent. So I wonder if adding 40+ layers to the map will cause the performance problem?
