I am making a webapp with OpenLayers and I want to use the localStorage

My map is displaying a route with a maxExtend bounding box. I know this
bounding box beforehand. So I need a mechanism to translate a Bounds
object into tile urls for each zoom level. Maybe someone can push me in
the right direction, or even has an example that does something similar?
Check out MobileMapStarter on Github. Look in cache.js specifically.
It saves to file storage, which isn't quite the same, but it does
include the logic for translating a bounding box into a set of XYZ tile
URLs.

Look for seedCache()
