Add an optional argument to urlretrieve to specify an etag for previously downloaded content:

    >>> urlretrieve('example.com/data.txt', etag="105800d-4af6-4c29d893d69c0")

That optional argument would add the following to the outgoing headers:

    "If-None-Match: 105800d-4af6-4c29d893d69c0"

If the site returns a 304 Not Modified, then the full content download isn't needed.

urlretrieve() is the old urllib interface. You probably want to improve the urllib2-inherited urlopen() instead.
