I am using OpenLayers (GeoExt) with google chrome browser. All WMS layer is for live database. I have refreshed the browser at certain interval using javascript but the data is cached in browser and when I refresh web page I see old data. When I clear cache from browser I see new data. How do I prevent caching or clear the cache automatically?
function RefreshPage(Period) {
setTimeout("location.reload(true);", Period);
}
