title: Proxy with urllib2
body: <p>I open urls with:</p>
  
  <p><code>site = urllib2.urlopen('http://google.com')</code></p>
  
  <p>And what I want to do is connect the same way with a proxy
  I got somewhere telling me:</p>
  
  <p><code>site = urllib2.urlopen('http://google.com', proxies={'http':'127.0.0.1'})</code></p>
  
  <p>but that didn't work either.</p>
  
  <p>I know urllib2 has something like a proxy handler, but I can't recall that function.</p>
