1. A method comprising:
- determining whether a tile object is stored in a first cache that is configured to store a plurality of tile objects associated with a map;
determining whether a resource locator associated with the tile object is stored in a second cache, if the tile object is not in the first cache; and
retrieving the tile object based on the resource locator if the resource locator is stored in the second cache,wherein the tile object includes a map image associated with a portion of the map, andwherein the map is a navigation and/or location map.

Abstract
A tile-map caching technique in which it is determined whether a tile object is stored in a first cache that is configured to store a plurality of tile objects associated with a map. It is also determined whether a resource locator associated with the tile object is stored in a second cache, if the tile object is not in the first cache. The tile object is retrieved based on the resource locator if the resource locator is stored in the second cache.
