GeoWebCache is a cache for WMS tiles implemented in Java.
Introduction
Maps are often static. As most mapping clients render WMS (Web Map Service) data every time they are queried, this can result in unnecessary processing and increased wait times. GeoWebCache optimizes this experience by saving (caching) map tiles as they are requested, in effect acting as a proxy between client (such as OpenLayers or Google Maps) and server (such as GeoServer, or any WMS-compliant server). As new maps and tiles are requested, GeoWebCache intercepts these calls and returns pre-rendered tiles if stored, or calls the server to render new tiles as necessary. Thus, once tiles are stored, the speed of map rendering increases many times, making for a more seamless user experience.
GeoWebCache is one of the easiest ways to accelerate your WMS mapping server and provide data for clients like Google Maps, Virtual Earth and Google Earth.
GeoWebCache is based on JTilecache, a Google Summer of Code project by Chris Whitney. It is currently developed by OpenGeo, the geospatial division of The Open Planning Project.
