Hi, I'm looking a bit into the GWC integration with GeoServer and it seems that the trick we used to avoid caching empty tiles is not working anymore.
The trick was to return a HTTP 204 when GS generated an empty tile, and that resulted in GWC skipping that tile and the whole subtree under it. However, as far as I can see that has been not working anymore since a long time, basically, since the time we switched off superoverlay as the default mode. As far as I can see the only code that returns a 204 is in the superoverlay encoders, but those are not run anymore by default. I guess we should do the same and return a 204 also in "download" mode when we see the tile is empty? At least, the request that I see GWC making is a plain GetMap in KML format, which should behave in "download" mode, no?
