Requests problem

[ZarKx]

Hi,
I'm trying to connect to a website with requests library.
This is my code :

import requests

url = 'http://www.website.com'

values = {
    'loginForm': 'loginForm',
    'loginForm:login': '',
    'loginForm:password': '',
    'loginForm:submit': 'Valider',
    'javax.faces.ViewState': 'j_id2'
}

with requests.Session() as s:
    response = s.post(url, data=values)
    print(response.text)

When i'm executing this one, it will redirect me at the same page, login form. I don't know why.
Did I forgot something ?

Here are informations I sent when I submit form.



Thanks for your help
