EnersunWebCache (EWC) is a project realized by adopting Java and used for caching WMS (Web Map Service) Tiles. When a map client requests for a new map and Tiles, the EWC intercepts certain calls and then returns cached Tiles. If caches are not found, the Tiles in a server are called, so that the map display speed is increased and better user experience is realized. The map is often static, and the operations of requesting for WMS data by most clients each time are doubted, so that unnecessary processing is caused and the waiting time is prolonged. The EWC optimizes the stored (cached) map tiles as agents for connecting the client (such as OpenLayers or Google map) with the server (such as GeoServer or any server compatible with WMS) when the clients make requests. With the requests of the new map and the tiles, the EWC intercepts the requests and pre-renders the tiles if the tiles are already cached. Therefore, once the tiles are stored, the map drawing speed can be increased by multiple times and perfecter user experience is realized.
