Summary: urllib2 fails with proxy requiring auth

Initial Comment:
The following program:

import urllib2

proxy_info = {
    'user' : 'my_name', 'pass' : 'my_pass',
    'host' : "my-proxy", 'port' : 80
}
 
# build a new opener that uses a proxy requiring
# authorization
proxy_support = urllib2.ProxyHandler(
    {"http" :
     "http://%(user)s:%(pass)s@%(host)s:%(port)d"
     % proxy_info})
opener = urllib2.build_opener(proxy_support, 
urllib2.HTTPHandler)
 
# install it
urllib2.install_opener(opener)
 
f = urllib2.urlopen('http://www.python.org/')
print f.headers
print f.read()


fails with the following error on Python 2.1b2 (on 
Windows)

C:\Data>python21 proxy_auth.py
Traceback (most recent call last):
  File "proxy_auth.py", line 18, in ?
    f = urllib2.urlopen('http://www.python.org/')
  File "c:\applications\python21\lib\urllib2.py", line 
135, in urlopen
    return _opener.open(url, data)
  File "c:\applications\python21\lib\urllib2.py", line

    '_open', req)
  File "c:\applications\python21\lib\urllib2.py", line

    result = func(*args)
  File "c:\applications\python21\lib\urllib2.py", line 
823, in http_open
    return self.do_open(httplib.HTTP, req)
  File "c:\applications\python21\lib\urllib2.py", line 
801, in do_open
    raise URLError(err)
urllib2.URLError: <urlopen error host not found>

A similar error occurred in beta 1, but this was 
reported as bug 406683. The fix is in beta 2. I 
applied the fix manually in beta 1, and it worked, so 
I can only assume that something else changed in the 
transition from beta 1 to beta 2, which broke this 
again.
