Mam problem, a mianowicie dlaczego ten skrypt nie pobiera strony onetu??

[php:1:eaddc59f28]<?php
$url = "onet.pl";
$user_agent = "Opera";
$proxyname = "los.micros.pl";
$proxyport = "80";
$ch = curl_init();
curl_setopt ($ch, HttpProxyTunnel, "$proxyname:$proxyport");
curl_setopt ($ch, CURLOPT_PROXY, "$proxyname:$proxyport");
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_USERAGENT, $user_agent);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_TIMEOUT, 10);
$result = curl_exec ($ch);
curl_close ($ch);
echo $result;

?>[/php:1:eaddc59f28]
Co należy zmienic??
