Login in un altro sito via Php

[dottwatson]

Ciao a tutti,
sto tentando di completare il login in un sito diverso da quello dove risiedono i miei script.
Ho tentato sia con la classe Snoopy che con le funzioni cURL ma il risultato non è cambiato (ho provato a replicare gli header che vengono generati dal browser) e il login fallisce.
Grazie.


Codice con Snoopy:

include "Snoopy.class.php";
$snoopy = new Snoopy;

$submit_url ='http://dominio/login.htm';
$snoopy->fetch($submit_url);
$snoopy->referer = "http://dominio/login.htm";

$submit_url ='http://dominio/index_html';
$submit_vars["do_login"] = "1";
$submit_vars["user"] = "utente";
$submit_vars["password"] = "password";
$submit_vars["Submit"] = "::: Accedi :::"; $snoopy->submit($submit_url,$submit_vars);

$snoopy->setcookies();
$submit_url ='http://dominio/invia.htm';
$snoopy->fetch($submit_url);
echo $snoopy->results; 

Codice con cURL:

class cURL {
    var $headers;
    var $user_agent;
    var $compression;
    var $cookie_file;
    var $proxy;
    function cURL($cookies=TRUE,$cookie='cookies.txt',$compression='gzip',
$proxy='') {
        $this->headers[] = 'Accept: HTTP Accept=text/html,application/xhtml 
+xml,application/xml;q=0.9,*/*;q=0.8';
        $this->headers[] = 'Accept-Language: it-it,it;q=0.8,en- us;q=0.5,en;q=0.3';
