Yup might be something about IIS. Seems that proxy is set up fine, and
geoserver is working ok.
But when you run
http://84.205.237.73/script/proxy.py?url=http://84.205.237.73:443/geoserver/wms?REQUEST=GetFeatureInfo&EXCEPTIONS=application%2Fvnd.ogc.se_xml&BBOX=142.52861%2C-44.59531%2C149.785355%2C-38.626637&X=567&Y=316&INFO_FORMAT=text%2Fhtml&QUERY_LAYERS=tasmania&FEATURE_COUNT=50&Layers=tasmania&Styles=&Srs=EPSG%3A4326&WIDTH=800&HEIGHT=658&format=image%2Fpng
you get:
Some unexpected error occurred. Error text was: <urlopen error [Errno
10060] A connection attempt failed because the connected party did not
properly respond after a period of time, or established connection
failed because connected host has failed to respond>
What does ur IIS log say? Sorry but dont know much about IIS, always
used apache or in J2EE environment.
Maybe here are some users that set it up on IIS??
