[MapProxy] configuring tiled WMS source

[Stephan Knauss]

Hi,

I try to configure a tiled-wms source so I'll be able to use this in a 
client unable to handle tiled wms.

I try to get the Landsat layers. http://onearth.jpl.nasa.gov/tiled.html

My source is configured like this:
sources:
   landsat_wms:
     type: wms
     req:
       url: http://wms.jpl.nasa.gov/wms.cgi?
       layers: global_mosaic

Is mapproxy able to do this at all? The documentation says it can do WMS 
tiling, but does this also apply to its own requests?
