I've created a grouped layer made from 4 MrSID rasters. I have a Openlayers map with basic Google layer. When I preview the grouped layer in geoserver , I see that tiles are being created in the GWC folder (tried both EPSG:4326 and EPSG:900919).
When I view the layer in my openlayers application (on same localhost machine) , no cached tiles are being created (I've cleared the browser cache to make sure the tiles are being generated from geoserver).
In my Openlayers I'm using GeoExt2 ... but still its regular WMS call.
Any idea why no tiles are being generated ?!
