chelelch

die Frage ist:
Stimmt was mitt der Syntax der Anfrage nicht ?
oder mach ich im Code irgendwas falsch ?
Vielen Dank für eure Mühe

Shade Of Mine

Die Antwort steht in der Fehlermeldung.

Du kannst auf dem HTTPS Port keine HTTP Anfrage hinsenden. Du musst das schon korrekt mit SSL/TLS Verschlüsseln. Dein Websniffer wird das Transparent für dich machen.

Herzichen Dank!
