问题

回答1:

Have a look at chapter 11.7. Handling redirects from the Dive Into Python series. It explains your entire issue in quite a bit of detail, example code and all.

回答2:

What are you currently using? Both urllib and urllib2 should handle it automatically:

page = urllib.urlopen('http://mrozekma.com/302test.php')
>>> print page.geturl()   # This will show the redirected-to URL
http://mrozekma.com/302test.php?success
>>> print page.readlines()
['Success']

If you are using the http.client.HTTPConnection(3.x), or httplib.HTTPConnection(2.x), just obtain the Location Header:

response.getheader('Location')

I know this works at least on craigslist.org
