  >>> h = httplib.HTTP("www.cnn.com", 80)
  >>> h.putrequest('GET', "/")
  >>> h.endheaders()
  >>> c, m, h = h.getreply()
  >>> c
200
  >>> m
'OK'
  >>> h
<httplib.HTTPMessage instance at 0x7ff3414c>
  >>> h.getheaders("content-type")
['text/html']

The above shows you the basics of using httplib - if your own server 
isn't responding that's probably not the library's fault. What is the 
server? Perhaps its implementation of the HTTP protocol is slightly off, 
but not so far off that browsers can't work with it.

For what it's worth you *do* appear to have formed the calls correctly, 
so something a little more complex is going on here.

You might consider using WireShark (nee Ethereal) to look at the data 
passing across the wire when you use the browser and when you use 
httplib then comparing the data. That won't work on Windows because it 
disobligingly refuses to let you tap into the loopback (127) network.
