Hi guys. I'm following this loosely, along with some other threads.
There is another one going on right now which also talks about authentication, hijacking JSESSIONID etc..

Gregor, what is not very clear to me, and maybe you want to do a wrapup, is what exactly you are - and are not - trying to achieve. For example, /why/ you want the users to login, and /if/ you want this one login to be valid for your 4 websites/applications (say "convenience SSO") or not. And /if/ you want that one user, having logged-in once today, should be able to re-access the same application later on without re-logging in, if in the meantime he went to have a long lunch, or closed his browser etc.. Or if you want a login just to block robots from accessing the site, or if you want a login just so that you can track a user for reasons of statistics and so on. From earlier explanations, it does not seem that you really have any confidential information to protect, nor that you are too worried about someone hijacking a user session etc.. And, if you want users to login, how are you giving them a user-id and password to login ?

I'm just mentioning all this because I generally get the feeling that you are not too hot on using HTTPS and CA certificates on all these sites, and maybe you don't really need to, for what you want to achieve.

Unless I am mistaken, I don't think that using HTTPS in order to protect the user-id/password from eavesdropping by some miscreant, you necessarily have to have a Verisign certificate for each site. Again unless I am mistaken, a CA-signed certificate is meant to be used to reassure the client that he is really talking to the server you say you are, and not some other impersonating phishing site. But it is not a prerequisite for simply making a connection through HTTPS.
Or ?
