I do not have a geowebcache at the moment; does not one come with a geoserver install these days? To confirm the code is still working I used this WMS-C service: - http://labs.metacarta.com/wms-c/tilecache.py?SERVICE=WMS&VERSION=1.1.1&REQUEST=GetCapabilities&tiled=true (from the data wiki page). >> >> Please note that uDig *will* allow you to choose any zoom at all; so the >> closest set of tiles will be featch and stretched onto the screen.
