title: urllib2.urlopen(): getting the size of the content
body: <p>Still working my way round python whenever work permits it...</p>
  
  <p>I'm querying a load of internal webUI's using a script that uses <code>urllib2.urlopen</code>. I'm wondering how it is possible to get the size of the page content from each request. I can't seem to figure this one out.</p>
  
  <p>Thanks in advance,</p>
