Thanks Arne.
Ok, then, perhaps there is a way to disable the automatic geowebcache
configuration generation in the GeoServer implementation?
>From the GeoServer docs:
http://geoserver.org/display/GEOSDOC/5.+GWC+-+GeoWebCache
*"The integrated version of GeoWebCache automatically configures every layer
with the two most common projections:*
- *EPSG:4326 (standard Latitude/Longitude)*
- *EPSG:900913 (Spherical Mercator, the projection used in Google Maps)"*
Thanks!
