Hallo!
Ich möchte folgendes gerne per PHP realisieren:

Ich suche ein PHP-Script, das wie ein Proxy funktioniert! Folgendermassen soll das Script laufen:

1) Script aufrufen (gewünschte Seite wird z.B: per URL übergeben)
2) Script lädt sich vom angegeben Server alle Daten des Zielservers auf den Server, auf dem das PHP Script läuft (natürlich nur die Sichtbaren Elemente (Grafiken, HTML Code usw).
3) Die Seite wird dann an den Browser weitergeben (natürlich muss sie aus den Seiten auf dem Script-Server erstellt werden)

Wäre natürlich klasse, wenn die Links, die man anwählt, dann genauso übertragen werden (Von Original-Server auf Script-Server laden und dann an Browser weitergeben)!

Gibt es sowas?
Habe ein Projekt auf Source-Forge gefunden, jedoch kann man das nicht wirklich!

Dankeschön für die Hilfe!

Falls dir Apache mit dem Modul „mod_proxy“ zur Verfügung steht, könntest du das Ganze ohne PHP abwickeln.

Ist noch nicht ganz fertig, aber es funktioniert zum Teil schon.
Hab schon eine Weile nicht mehr dran gearbeitet, weiss also nicht genau was jetzt alles laeuft und was noch fehlt.
Die verwendete Klasse gibt's hier.
phpproxy.php

PHP-Code:
