Ich habe noch ein arbeitsloses IP Switch herum liegen, das ich gerne mal über IPS steuerbar machen möchte. Das Gerät hat ein Webinterface, bei dem man sich zunächst anmelden muss. Nach der Anmeldung (wenn auch nur mit einem leeren Passwort) merkt sich das Gerät den User nicht anhand einer Session, sondern mit SID’s hinter jedem Link. Wenn ich eine Zeit lang keine Aktion gemacht habe, dann lande ich wieder auf der login Seite, muss mich neu anmelden, und es werden neue SID’s generiert.
hier mal der Seitenquelltext des Interfaces, wenn ich schon eingeloggt bin:

<script language=JavaScript>
function onClose()
{
var top=self.screenTop;
if (top>9000) {
window.open('logout.htm?sid=0034600130');
self.blur();
}
}

Wie kann ich hier ansetzen es ins IPS einzubauen? Muss ich vor jeder Aktion den Webinhalt parsen, erkennen, ob ich „noch“ eingeloggt bin oder neue Login Anfrage zwischensenden muss, die SID in eine Variable speichern und sie bei jeder zukünftigen Aktion mitsenden?
Oder gibt es einen schöneren Weg?
Sauberer wäre es vermutlich nach jeder Aktion ein Logout zu senden und jedes mal neu einloggen…
Oder gibt es da was einfacheres?
