urllib2.py, after receiving an HTTP response, decides if it was an error
and raises an Exception, or it just returns the info.
For example, you make ``urllib2.urlopen("http://www.google.com";)``. If
you receive 200, it's ok; if you receive 500, you get an exception
raised.
How it decides? Function HTTPErrorProcessor, line 490, actually says:
class HTTPErrorProcessor(BaseHandler):
...
if code not in (200, 206):
# it prepares an error response
...
Why only 200 and 206? A coworker of mine found this (he was receiving
202, "Accepted").
In RFC 2616 (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html) it
says about codes "2xx"...
This class of status code indicates that the client's request was
successfully received, understood, and accepted.
I know it's no difficult to work this around (you have to catch all the
exceptions, and check for the code), but I was wondering the reasoning
of this.
IMHO, "2xx" should not raise an exception. If you also think it's a bug,
I can fix it.
