All the session data is stored on the server either in a database, file
or memory against a unique ID value. The server handles how this is
done, and it's likely you won't ever need to get involved with changing
how it does things.
>From the client-side of things; the user agent (browser) sends this
unique ID either as part of the URL or with the headers as a post
variable, which is why you may see a PHP_SESSION_ID (or something
similar) index in the $_REQUEST array when you use session_start() in
your scripts.
Has this helped?
