[OpenLayers-Users] Pre-seeding localStorage

[Jurrie Overgoor]

Hello everyone,

I am making a webapp with OpenLayers and I want to use the localStorage 
for offline situations. I want to give the users the ability to preload 
the tiles in the localStorage. I'm thinking of a 'preload' page that 
displays a progressbar per zoomlevel, and starts with zoomlevel X (loads 
all the tiles for zoomlevel X) and continues with zoomlevel X+1. It 
would stop when all zoomlevels are done, or when the localStorage is 
full. How do I go about this?

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?

I hope I've explained my problem clear enough. Thanks in advance for any 
help!

With kind regards,

Jurrie
