 * per-feed settings
 * cron download of the feed when expiring (not when requested by user)
 * http://dev.openlayers.org/docs/files/OpenLayers/Strategy/Refresh-js.html
 * build into OL (done)
 * link to cache refresh time

{{{
var kmlLayerExercise_24_Injects_Strategy=new OpenLayers.Strategy.Refresh({interval:120000});
kmlLayerExercise_24_Injects_Strategy.setLayer(kmlLayerExercise_24_Injects);
kmlLayerExercise_24_Injects_Strategy.start();
