[MapProxy] Problems configuring MapProxy to serve WMS layer

[Oliver Tonnhofer]

Hi,

the BBOX (-506.77734375,-266.8359375,370.01953125,190.1953125) _is_ in EPSG:4326. You are just a bit too far zoomed out and the OpenLayers demo client will request that BBOX without any clipping. MapProxy doesn't know the extent of the cascaded service with your first configuration and forwards the requested BBOX to Mapserver. The second configuration contains an extent from the GLOBAL_MERCATOR grid and MapProxy can clip the BBOX.

You can get the first example to work if you add a coverage to your source: http://mapproxy.org/docs/latest/coverages.html

Regards,
Oliver
