urllib2 and Set-Cookie with "302 Moved temporarily"

[=?ISO-8859-1?Q?Eino_M=E4kitalo?=]

It seems that urrlib2 default redirection does not allow me to handle
Cookies. Service I'm trying seems to use IP switcher and session id's
with cookies. After successful login it changes session id
(PD-H_SESSION-ID) in 302 Moved temporarily. Urllib2 is so clever that it
handles redirection but with wrong cookies.


Some hookings? Just own version from source.
What is the most lazy way to handle this. Older urllib?

It seems that urrlib2 default redirection does not allow me to handle
Cookies. Service I'm trying seems to use IP switcher and session id's with cookies. After
successful login it changes session id (PD-H_SESSION-ID) in 302 Moved temporarily.

and adds a new cookie.

Urllib2 is so clever that it handles redirection but with wrong cookies.

with the old cookies, that is. that's stupid.

here's an ugly hack for the old urllib that looks for set-cookie headers in
redirects, and adds corresponding cookie headers to the new request:

import urllib

class my_url_opener(urllib.FancyURLopener):

def http_error_302(self, *args):
headers = args[4]
# print headers # <-- uncomment to see the headers
cookie = headers.get("set-cookie")
if cookie:
# this is ugly
self.addheaders.append(("Cookie", cookie.split(";")[0]))
return urllib.FancyURLopener.http_error_302(self, *args)

myurlopen = my_url_opener().open

myurlopen("http://www.google.com")

</F>

# this is ugly

Yes, but short and easy. Thanks.
