This project is now called GeoWebCache, and has moved to http://geowebcache.org.
Using GeoServer to serve geographic image tiles directly to a web client (such as OpenLayers) requires substantial computational effort on the server side. Yet, the redundant and largely static nature of the problem makes it an ideal candidate for a cache. Existing naive HTTP caches are often employed, but are not well tailored to the specific needs of WMS image tile requests. One existing WMS-C (Web Mapping Service Caching server) exists: MetaCarta"s TileCache. TileCache provides a significant performance improvement for serving map tiles. However, TileCache is typically run using mod_python, an environment that requires much considerable setup in addition to a J2EE deployment of GeoServer. In response to these needs,
