What you got from HTTP_COOKIE was a _string_ (or None). You then need to
turn it into a cookie:

     cookie_string = os.environ.get('HTTP_COOKIE')
     if cookie_string:
         cookie = Cookie.SimpleCookie(cookie_string)
         ...
     else:
         cookie = Cookie.SimpleCookie()
         ...
