Does Python Urllib2 Library Use The IE Proxy Setting Default On Windows?

I noticed the urllib2 library used my IE proxy setting. Any official explanation for this? Thanks a lot.

Solution 1:

See the urllib2 section on ProxyHandler.

The default is to read the list of proxies from the environment variables <protocol>_proxy. If no proxy environment variables are set, in a Windows environment, proxy settings are obtained from the registry’s Internet Settings section and in a Mac OS X environment, proxy information is retrieved from the OS X System Configuration Framework.
