[OpenLayers-Users] Tiles and border

[Peter Peterse]

Hello all,

it looks like I have a problem with loading tiles. When I change my zoom
level, I see (with firebug) tiles being downloaded which I can't see
direct on my screen.
My TMS options are:
 { type:'jpg',
   getURL:get_osm_url,
   border:0,
   transitionEffect: 'resize',
   projection:new OpenLayers.Projection("EPSG:28992")
 }

Am I right that the option border mean that tiles which are out of my
window shouldend be downloaded jet?

An other question is, how can I enable caching the downloaded tiles?

Thanks for your help.

Regards,
Peter.
