[C] HTTP-Request Probleme !

[luxury11]

Beschäftige mich gerade mit dem http-Request
und habe mir ein "Programm" geschrieben, das mir Probleme bereitet.

Ich sende zuerste meine Parameter an den Host
und empfange folgendes:



Statt / habe ich auch index.html und index.php genommen und bei anderen hosts versucht.

Hier der aktuelle Text.
