I'm trying to get some content automatically from a site using requests (and bs4)

I have a script that gets a cookie:

def getCookies(self):
    username = 'username'
    password = 'password'
    URL = 'logonURL'
    r = requests.get(URL, auth=('username', 'password'))
    cookies = r.cookies

dump of the cookies looks like:

<<class 'requests.cookies.RequestsCookieJar'>[<Cookie ASP.NET_SessionId=yqokjr55ezarqbijyrwnov45 for URL.com/>, <Cookie BIGipServerPE_Journals.lww.com_80=1440336906.20480.0000 for URL.com/>, <Cookie JournalsLockCookie=id=a5720750-3f20-4207-a500-93ae4389213c&ip=IP address for URL.com/>]>

But when I pass the cookie object to the next URL:

 soup = Soup(s.get(URL, cookies = cookies).content)

its not working out - I can see by dumping the soup that I'm not giving the webserver my credentials properly

I tried running a requests session:

def getCookies(self):
    self.s = requests.session()
    username = 'username'
    password = 'password'
    URL = 'logURL'
    r = self.s.get(URL, auth=('username', 'password'))

and I get the same no joy.

I looked at the header via liveHttp in FF when I visit the 2nd page, and see a very different form: 

Cookie: WT_FPC=id=264b0aa85e0247eb4f11355304127862:lv=1355317068013:ss=1355314918680; UserInfo=Username=username; BIGipServerPE_Journals.lww.com_80=1423559690.20480.0000; PlatformAuthCookie=true; Institution=ReferrerUrl=http://logonURL.com/?wa=wsignin1.0&wtrealm=urn:adis&wctx=http://URL.com/_layouts/Authenticate.aspx?Source=%252fpecnews%252ftoc%252f2012%252f06440&token=method|ExpireAbsolute; counterSessionGuidId=6e2bd57f-b6da-4dd4-bcb0-742428e08b5e; MyListsRefresh=12/13/2012 12:59:04 AM; ASP.NET_SessionId=40a04p45zppozc45wbadah45; JournalsLockCookie=id=85d1f38f-dcbb-476a-bc2e-92f7ac1ae493&i
