Chris,
The url is not changed when I point to http://www.mydomain.com/login.html in
browser. The .html is mapped to servlet. I expected it to change to https://....
So it is not secure to start as http and then switch to https to use the same
http session because session id to visible to man-in-the-middle. Am I right? If
not secure, why is it allowed to be working this way?
Even start with https, if url-rewriting is used for session
tracking(sessionid in url), it is not secure anymore, right?
Thanks,
Dave

It's possible that Tomcat ignores that setting during its own
authentication process (which would suck if it were the case). What the
the URL say when you are being asked to login?

Well, it's not a "http session" per-se... it's the session that was
created while you were in http mode. The answer is yes: Tomcat will
continue to use that session. If, however, you kill any sessions
(yourself) as you switch to https, then any fallback to http will lose
the session (because the browser will refuse to send a "secure" cookie
through a non-secure channel.

This does not require man-in-the-middle. It's just plain-old session
hijacking. This can happen whether you are using SSL or not -- if
someone can guess your session id, you're pwned.
