The AspMap 4.3 release contains the following features.

Server-side API:

• Map caching:
  Map caching is an effective way to make your mapping application run faster. When you deploy cached maps, your users spend less time waiting for the map to draw (during pan and zoom operations). AspMap distributes cached images whenever someone asks for a map. It is much quicker for AspMap to hand out a cached image than to draw the map each time someone requests it. Map caching is implemented by all popular Internet mapping sites, with map caching offered by AspMap, you can achieve similar performance for your maps.
