Part of my question may be academic but, like many technical things, it becomes practical when getting into the details. I currently have 20 - 30 GB used by geowebcache for SRS 900913 (total for about 12 raster layers). When a request comes in using 3857, it will not use the 900913 cache. To

I've been starting to use GeoServer caching (geowebcache) more often and have a question regarding the caching for the web mercator or Google projection. The official EPSG code for the web mercator projection is EPSG:3857. GeoServer does support this by default. However, geowebcache uses

John, a truly academic question. Yes - in theory. However, the widespread use of 900913 is a result of the Cinderella treatment of Google by the spatial fraternity and the past confusion with EPSG:3587 and EPSG:3857. What geowebcache uses as a default is entirely up to you because in the
