title: Form based authentication with twisted.web
body: <p>Can anybody point me to a simple example about how to implement form based authentication with twisted.web? I only found <a href="http://blog.vrplumber.com/index.php?/archives/1640-Adding-user-authentication-to-your-Twisted-web-site-Another-HowTo-for-undocumented-features....html" rel="nofollow">http://blog.vrplumber.com/index.php?/archives/1640-Adding-user-authentication-to-your-Twisted-web-site-Another-HowTo-for-undocumented-features....html</a> which seems to be quite old.</p>
  
  <p>Update: As Jean-Paul asked for, I'll try to be a bit more specific. I'm looking for a simple starting point, which allows me to use my own user database to check credentials. So idealy I would like to have some module or library, which handels secure cookies, storing and checking salted passwords, ... which can easily be integrated into twisted. Just imagine you have a small web app where you can register for an account and login afterwards. How would you do something like that with Twisted. No fancy "enterprise" requirements like AD or so.</p>
