Ich verwende aktuell folgenden Code (aus Forum und PureArea) um Content (genaugenommen HTTP Ausgaben eines PHP Scriptes) vom Internet auszulesen. Das charmante an diesem Code ist, dass es die Einstellungen (Proxy etc.) und auch SSL für HTTPS alles von selbst erledigt.
Jetzt sollte das ganze aber nach Linux portiert werden. Hat jemand eine Idee wie ich eine solche Funktion unter Linux erhalten kann? Ich habe leider keine Ahnung von Linux API...
Hier mein Windows-Code:

#INTERNET_FLAG_NO_CACHE_WRITE = $04000000
