Yeah, the case you describe is very similar to the one for which this feature was written. And now I do see you said it in one of the follow ups I obviously missed, sorry. That is the only way forward that I can think of. And tell all of the providers to switch to clusters of GeoServers for inc

Hi Arne The reason is that we collect WMS from different providers. The idea with caching is, that we have a "copy" of the data in our cache - und can serve our system with this, when one of the "source WMS" of which we haven't any control, isn't working. I'm not sure if this is really possible?

I've read the followups, but it is stilll unclear to me why you are invoking GWC at all ? GWC stores many small tiles in PNG or JPEG format. It is rather expensive to decode these tiles and to combine them into a new image. Last time I checked it was a lot slower than using an optimized GeoTIFF

Christian, Jukka pointed you in the correct direction. However, I would strongly advise a) to stick to one of the scale sets in the OGC WMTS standard, b) to ask your users to get them using the getCapabilities statement and only look at them using the correct scale/resolution and c) ask them not t
