The SID constant contains the session identifier that is to be added to a
link, IF NECESSARY.
This said: PHP normally uses cookies to transfer the session ID to the
client browser (controlled by the ini file setting "session.use_cookies").
If the client browser returns a session cookie there's no need for PHP to
rewrite the URL links, thus SID is empty. If the client browser does NOT
return a session cookie, SID contains the necessary information for URL
rewriting.
If you need to generate the SID value regardless of cookie/non-cookie
settings, use
$sid = session_name() . '=' . session_id();
All this can be found at http://www.php.net/manual/en/ref.session.php and
the following pages.
