How to share session with IE

I found some similar topics in the newsgroup and get some ideas from

According to all you suggestions, there are at least two ways to get my

1. Use the cookie of IE, so I don't need to code to logon. That means I
must use ClientCookie. I found some example in the docs and the
newsgroup. Below is some code based on the docs of ClientCookie. But
the page I get is still the page told me must login ( I CAN get the
right page in IE).

    import ClientCookie, urllib2

   #the page I want to get

    cj = ClientCookie.MSIECookieJar(delayload=True)
    print cj          #I want to know what I get

    opener =
    f = ClientCookie.urlopen(url_string)
    print          # NOT the right page html

2. Logon myself by python. First, I access the login page and submit
the form of username and password. The form has many fields other than
username and passwd, so the dict "data" has all the fields even if it's
hide. Then, if the login succeed, I can get my page use the opener with

    import urllib2, cookielib

   #the page I want to get
     #the login page

    headers =  {'User-agent' : 'Mozilla/4.0 (compatible; MSIE 5.5;
Windows NT)'}
    cj = cookielib.CookieJar()
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))

    data = {
        'formhash': '3bd8bc0a',
        "referer" : "index.php",
        "loginfield": "username",
        'username': 'myname',
        'password': 'mypass',
        "questionid": 0,
        "cookietime" : "315360000",
    req=urllib2.Request(url_login, urllib.urlencode(data), headers)
    f =
    print req.get_data()
    print req.header_items()

    ## if login succeed, I can get my page url_string)

However, both ways didn't work for me. I don't know what's wrong. If
it's because the server page check the header or the submit of the form
is wrong?

I didn't study Mechanize module yet. I want a solution as simple as
possible for distribution reason.
