Hi Esteban,
Sorry, I wasn't clear, I wasn't suggesting asking for larger tiles (I
don't think GWC supports them anyway). I was suggesting requesting
*more* tiles.
If a 1024 pixel monitor needs 4*4 tiles width to fill it, then on a
retina display you could request twice as many tiles in each dimension -
so 8*8, and then scale suitably. At least, in theory. I guess that's
effectively what the 512 thing you're looking at is doing too, but using
larger tiles rather than making more requests. No idea how to make the
client make such requests though.
Cheers,
Jonathan

Hi Jonathan, as I pointed out previously we need it to work with the
google maps service provided by GWC, which does not accept tiles
larger than 256x256, are vector tiles supported by google maps?
We already tried using GeoJSON, but for large datasets is very slow,
so we moved to tiles.
Thanks
Esteban

Hi,
I don't believe so (others likely know better of course!). I
believe the only way to do this with GeoServer / GWC would be to
simply request more tiles using the client and then scale
appropriately.
As of GeoServer 2.11.x (which is in RC right now
http://blog.geoserver.org/2017/03/14/geoserver-2-11-rc1-released/
<http://blog.geoserver.org/2017/03/14/geoserver-2-11-rc1-released/> ),
there is support for Vector Tiles -
http://docs.geoserver.org/latest/en/user/extensions/vectortiles/index.html
<http://docs.geoserver.org/latest/en/user/extensions/vectortiles/index.html>
- that would be another option. The rendering would be done client
side so you could control the DPI; I don't know if whatever client
mapbox uses could be pointed at this output instead.
Cheers,
Jonathan

Hi, I need the gmaps service of geowebcache to return tiles
for retina display (2x 512x512).
For example in mapbox you can specify it in the query string,
is there a similar feature for geowebcache?
