Doesn't save sid

[xDaizu]

If I understand the protocol correctly, $sid should be somehow persisted so it doesn't create a new sid for the same user every time you call the binding.php file.

Well, I followed your example (adding $username and $password variables and an echo at the end)

require_once "lib/XmppPrebind.php";


$username = "test";
$password = "test";

$xmppPrebind = new XmppPrebind('localhost', 'http://localhost:5280/http-bind/', null, false, true);
$xmppPrebind->connect($username, $password);
$xmppPrebind->auth();
$sessionInfo = $xmppPrebind->getSessionInfo(); // array containing sid, rid and jid

echo json_encode($sessionInfo);

and every time I run it, it gives me a different sid. Where is it supposed to save it? And, if it doesn't, (i could save it myself) how do I inject it back in the next run?
