Summary: urllib2 raises exception with non-200 success codes.
Initial Comment:
If a server returns a code other than 200, specifically 201
(Created), urllib2.urlopen will raise an HTTPError exception. I ran
into this while implementing an Atom API client, which solicits 201
responses from the server when submitting a blog post.

Before bug 912845 (CVS rev 1.69) added 206 to the list of
response codes considered "successful" by urllib2, I'd
assumed this would never be altered, for
backwards-compatibility reasons.
Note that this behaviour can be configured by module users,
since HTTPError exceptions support the urllib2 response
interface. This can be done by replacing
HTTPErrorProcessor, or by replacing HTTPDefaultErrorHandler,
or catching the exception "manually".
But maybe since the 206 issue was considered a valid bug
fix, this is OK too.
If so, it would be best if the other 20x responses were also
considered at the same time.
