WMS Help please

[Stephen Woodbridge]

Hi all,

Just downloaded and built mapserver 4.10 and I'm have a strange problem 
with a WMS Layer.

The apache error log says:

libpng warning: Incomplete compressed datastream in iCCP chunk
libpng warning: Profile size field missing from iCCP chunk

If I load the URL directly into the browser is returns fine, but from 
mapserver I get

HTTP: HTTP GET request failed with status 403 () ... from above.

The layer definition looks like:

   LAYER
     NAME "JPL-WMS"
     TYPE RASTER
     DEBUG TRUE
     STATUS DEFAULT
     CONNECTION "http://wms.jpl.nasa.gov/wms.cgi?STYLES="

       "wms_server_version" "1.1.1"
       "wms_format"         "image/png"
     END
   END


MapServer version 4.10.0 OUTPUT=GIF OUTPUT=PNG OUTPUT=JPEG OUTPUT=WBMP 
OUTPUT=SVG SUPPORTS=PROJ SUPPORTS=FREETYPE SUPPORTS=WMS_SERVER 
SUPPORTS=WMS_CLIENT INPUT=TIFF INPUT=EPPL7 INPUT=JPEG INPUT=POSTGIS

Anyone have a clue on what I'm doing wrong, or is this a bug?

Thanks,
