[Tutor] urllib2 with a proxy

[Kent Johnson]

I'm not familiar with this library but looking at your code and the docs I 
can make some guesses where the problem might be:
- The second argument to ProxyHandler should be a complete URL, e.g. 
'http://proxy:8080'. This is the cause of the exception you are seeing.
- Try using a HTTPBasicAuthHandler instead of a HTTPDigestAuthHandler 
unless you are sure your proxy uses digest authentication
- You should pass an instance of CacheFTPHandler to build_opener, not the 
class itself. In other words, pass CacheFTPHandler() with parentheses.
