That is how you use it IIRC, this installs the proxy handler into urllib
and subsequent objects you subclass from urllib will use the custom handler.

Lets take a step back. You had the following line...
request_object = urllib2.Request('http://www.example.com')
...You printed it and it showed that you had created a Request object
right. Now what happens when you type...
response = urllib2.urlopen(request_object)
print response
?
