You haven't said what you're really trying to do.

Constructing your own Cookie instances is rarely necessary or
sensible.  If you do, I recommend getting the constructor arguments by
inspecting the Cookie object the server actually returns, rather than
using the values you *think* you know are correct.

Please define "working".

If you want to handle cookies when opening URLs, just do this:

opener = urllib2.build_opener(urllib2.HTTPCookieProcessor())
opener.open("http://itay/temp.html")
# more .open() calls go here...


Of course, on the first HTTP request, cookie handling cannot have any
effect at all unless you've somehow loaded some old cookies first.
Your .open() may only involve a single HTTP request (though
server-side software may detect the absence of a cookie on the first
request, and do a page refresh or redirect so it can see its cookie
returned to it again; vanilla urllib2 handles redirects but not
refreshes; package ClientCookie handles the latter, amongst other
things).

Regardless, turning on cookielib and httplib debug output will likely
be helpful if you're stuck (if only to post the output to this
newsgroup):

import logging, urllib2, sys

hh = urllib2.HTTPHandler()
hsh = urllib2.HTTPSHandler()
hh.set_http_debuglevel(1)
hsh.set_http_debuglevel(1)
opener = urllib2.build_opener(hh, hsh, urllib2.HTTPCookieProcessor())
logger = logging.getLogger("cookielib")
logger.addHandler(logging.StreamHandler(sys.stdout))
logger.setLevel(logging.DEBUG)

response = opener.open("http://wwwsearch.sf.net/cgi-bin/cookietest.cgi")
