Taking actions after form-based authentication?

[Martin Mavrov]

    Hi,

I've been wondering how can programmer take some actions (for example to put
things in HttpSession)
after the user had authenticated itself via form? For instance - the user
tries to access some
protected resource, it is presented the authentication form, it enters
login/password and
is forwarded to the requested resource - how can I intercept that forward
action?
