[MapProxy] caching from a.tile.openstreetmap.org with mapproxy

[Christian Willmes]

Ok, found the one error myself. (sorry)

It has to be (changed x and y):
  osm_tiles:
    type: tile
    grid: GLOBAL_MERCATOR
    url: http://a.tile.openstreetmap.org/%(z)s/%(x)s/%(y)s.png

But z seems to be reversed.

See:

Can I solve this within the configuration or do I have to add code
somewhere to reverse the Z order?

Thanks and regards,

Christian
