Hi, I am trying to download some image data from a private WMS.

When I try to use gdal_translate I receive the following error (I had to
remove the server address):

ERROR 1: GDALWMS: Unable to download block 337235, 219173.
  URL:
http://SERVERADDRESS&request=GetMap&version=1.1.0&layers=Orthophoto%2CLuftbild_25cm%2CLuftbild_1m%2CLuftbild_4m%2CSatellitenbild_30m
&styles=&srs=EPSG:3857&transparent=TRUE&format=image/png&width=256&height=256&bbox=1545531.75694187,6010372.27699605,1545595.75694216,6010436.27699633
  HTTP status code: 0, error: Recv failure: Connection was reset.
ERROR 1: IReadBlock failed at X offset 337235, Y offset 219173

But when I copy the URL from the error message and use it in my browser it
works fine.

Here is the XML (I was not sure which parameters to use for the DataWindow.
I just chose SizeX/Y to be four times the extent because the resolution is
25cm.)
