New submission from Shawn Ligocki <sligocki at gmail.com>:

urllib2 sporadically falsely claims that http://www.bankofamerica.com/ has infinite redirect:


$ python -c 'import urllib2; print urllib2.urlopen("http://www.bankofamerica.com/").geturl()'
https://www.bankofamerica.com/

$ python -c 'import urllib2; print urllib2.urlopen("http://www.bankofamerica.com/").geturl()'
Traceback (most recent call last):

    self.inf_msg + msg, headers, fp)
urllib2.HTTPError: HTTP Error 302: The HTTP server returned a redirect error that would lead to an infinite loop.
The last 30x error message was:
Found



Since it is sporadic, it could just be a problem with bankofamerica.com's servers. Is there an easy way to see what response urllib2 got that made it unhappy?
