Oleg, The login seems to be successful. The reason is that authpost.getResponseBodyAsString() returns the javascript that re-directs the web site. It is the same javascript if I login to the site manually. I do not know why the session cookies are not generated corrrectly.
I use the traffic analyzer to capture the http traffic. The initial tries only give me the ip addresses, not to the details for http handshake. I need to spend more. Thank you very much !
