Abstract
An image tile server importantly includes an image tile cache, to support a tiled map display in a user device. Instead of the conventional user device client (e.g., an Ajax client) making image requests directly to a mapping server (MS), a display device initiates an image request of a tile server (TS), and the tile server returns the requested image. However, importantly, the tile server (TS) also retains a cached copy of the returned image for faster retrieval at a later time relating to another image request by the same or different user device.
