The session ID is pushed as a cookie if cookies are accepted by the browser.
Of course, IE 5.5 accepts cookies. If the cookie is refused, the server
generally use URL rewriting to track the session. The session ID coming back
to the server is refered as 'session ID being asked by the client' in the
servlet documentation. No matter how it is achieved, Java session tracking
will never work with IE 5.5. This is not really a problem if you are aware
of it and do your own session tracking. (I use identified session tracking
through PathInfo, storing HttpoSession objects in a HashTable. The main
drawback is having to take care of invalidation while this could be
automated with Java sessions.)
The real concern is for developpers who are not aware of this problem and
might rely on Java session tracking. It may take some times before they
realise their servlets are not "compatible" with IE 5.5 clients.
Another interesting question is "Why". Could it be a Microsoft decision ?

Sessions are usually handled with Cookies... A client doesn't usually "ask"
for a Session ID, but gets the value pushed in as a Cookie... Can you check
out that the browser is actually accepting cookies???
