Any tips are so much appreciated.
World base maps are normally not delievered via WMS, they are normally provided as cached tile: google/bing/yahoo, OSM, NASA and so on. OGC defines the WMTS protocol to serve cached tiles, but the common providers normally use their own custom protocol, and set some usage limitation either in terms of the type of client (typically, it must be a browser) or on the number of tiles you can read in a day by a singel IP (OSM does this too to prevent being overwhelmed). Both these limitations suggest you have the clients ask for the tiles directly, as opposed to your server. Anyways, if someone wanted to add tile cascading in GeoServer there is some code base sitting in uDig that could be backported to Geotools and then made available to GeoServer to read a variety of tile sources: http://jgrasstechtips.blogspot.it/2012/05/udig-web-map-tiles-enhancements.html Cheers Andrea -- Ing.
