Summary: urllib.py: open_http() host problem

Initial Comment:
While trying to use the httplib.py urlopen() function, 
as follows:

doc = urlopen("http://www.python.org").read()
print doc

I was receiving the following trace:

Traceback (most recent call last):
  File "C:/Documents and 
Settings/Administrator/Desktop/jason/grabpage.py", 
line 3, in ?
    doc = urlopen("http://www.python.org").read()
  File "C:\Python22\lib\urllib.py", line 73, in urlopen
    return _urlopener.open(url)
  File "C:\Python22\lib\urllib.py", line 178, in open
    return getattr(self, name)(url)
  File "C:\Python22\lib\urllib.py", line 283, in 
open_http
    h = httplib.HTTP(host)
  File "C:\Python22\lib\httplib.py", line 688, in 
__init__
    self._setup(self._connection_class(host, port))
  File "C:\Python22\lib\httplib.py", line 343, in 
__init__
    self._set_hostport(host, port)
  File "C:\Python22\lib\httplib.py", line 349, in 
_set_hostport
    port = int(host[i+1:])
ValueError: invalid literal for int(): 

I managed to track the problem down to the function 
open_http() in urllib.py. The value of the 'host' 
variable contained the string 'http:' rather 
than 'www.python.org', when a call is made as follows:

httplib.HTTP(host)

Line 272 of urllib.py should be setting the 
variable 'host' to the value of 'realhost' but the 
statement is never executed. The function 'proxy_bypas
()' doesn't appear to do anything but return 0.

I fixed it for my own purposes by adding a statement:

host = realhost
