GeoWebCache is a WMS tile cache implemented as a Java HttpServlet. It does automatic matching to the best available tile and supports JCS and file backends. The response time is typically measured in milliseconds.

Changes

GeoWebCache now uses the Spring framework for internal wiring, making it very pluggable. A new feature is that it can automatically configure itself based on a getCapabilities request to a WMS server, as well as support multiple projections per layer. Support for KML super overlays (Google Earth) has been added and the groundwork for vector overlays has been done.
