    Facebook Http WebRequest/Response Cookie Problem

    Hallo liebe VB Community,
    dies ist mein erster Beitrag und ich komme gleich mit einer Frage;)
    Ich arbeite im moment an einem Facebook - Freunde Ad Programm mit VB NET 2010. Wollte meinen Bot nicht auf Basis eines Form mit WebBrowser Tool sondern als kompakte Konsolenanwendung entwickeln mit HttpWeb Response/Request .

    Login - funktioniert soweit
    Jedoch hab ich irgendwas bei den Cookies falsch gemacht...
    Profil besuchen - und wir sind nicht eingeloggt, kommmen zwar aufs Profil aber ohne eingeloggt zu sein bzw wurden die Cookies nicht erkannt.

    Nun, wieso nimmst Du an, daß der Login funktioniert hat ? Mir sieht es eher danach aus als ob Du genau daran scheiterst, da Du sofort mit einem POST Request beginnst

    Versuchs mal in folgender Reihenfolge:
    - einen leeren Cookiecontainer anlegen
    - mit einem GET Request auf die Login Seite gehen (-> Cookiecontainer wird automatisch mit Sessioncookie gefüllt)
    - Login Daten ermitteln
    - mit einem POST Request und dem gleichen CookieContainer den Login durchführen

    Jetzt funktioniert der Login, und die Cookies werden gespeichert,
    Hab Testweise mal die zweite Funktion FBProfil() gestartet...
    Nun bin ich zwar eingeloggt aber es kommt der Fehler von Facebook "Leider konnte deine Anfrage nicht bearbeitet werden." ....
    was ist nun schief gelaufen.
