By persistent storage i meant....being stored in Hard Disk as some sort of
files. (As one can see some files in the cookies folder of IE which are
there always for some of the sites).

I don't think I'm following you -- like what you mean by "persistent
storage".
In any case, all the session information is stored on the server.
There just needs to be something in the request that allows the server
to pull up the correct session, and that is the session ID. That can
be done either by keeping the session ID in a cookie, or in the URL
using URL Rewriting (someone else mentioned that in another response
to your post). (At least, those are the built-in mechanisms the API
provides.)
If you use a cookie, the cookie is not stored persistently on the
client end, but goes away when the browser is exited. (At least, the
newer versions of the spec say this; I don't think older ones covered
it, so the behavior was left up to the servlet engine developer).
