    Hallo zusammen,

    bin absoluter Neuling was dieses Thema betrifft und brauche etwas Hilfe
    Habe eine kleine Testanwendung geschrieben, welche leider nicht das gewünschte Ergebnis liefert.

    Als Ergebnis würde ich folgendes erwarten

    Beim einem Client
    Antwort fuer Client: A

    Beim anderen Client
    Antwort fuer Client: B

    Leider bekommen beide das Ergebnis:
    Antwort fuer Client: A

    Hier der Code meines Testprogramms:
