[MapProxy] Unable to use OpenLayers.ProxyHost for protocol: OpenLayers.Protocol.WFS.fromWMSLayer(layer)

Fri Dec 24 04:32:32 EST 2010

Hello all

I am a new bee in open source development, for learning i start with the basic 
examples. I download the proxy.cgi, change it to proxy.py (Working with IIS), 
implemented each and every step on net. but I am unable to use proxy.py. when i 
check manually (http://localhost:80/proxy.py) it is giving 

Some unexpected error occurred. Error text was: <urlopen error (10061, 
'Connection refused')>

Iam using my college internet for this, which may contain firewalls. I kno it is 
a TCP/IP error.

My Question is can we use localhost as the proxy server.

below is my code, Thanks for any help in advance. As it keep my interest in Open 
source development
& learning
  I try calling WMS from both Geoserver on http://localhost:85 & from remote WMS 
also.

code:

type="text/css" />

 <script type="text/javascript">

            layer = new OpenLayers.Layer.WMS(
