La prova che ho effettuato è:
Codice PHP:
<?php
$url = 'http://iota09avatar.altervista.org/iota/?=avatar.gif';
echo '<h1>'.$_SERVER['SERVER_ADDR'].'</h1>';
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
curl_setopt($curl, CURLOPT_VERBOSE, true);
curl_setopt($curl, CURLOPT_STDERR, $verbose = fopen('php://temp', 'rw+'));
$html = curl_exec($curl);
echo "Verbose information:\n<pre>", !rewind($verbose), htmlspecialchars(stream_get_contents($verbose)), "</pre>\n";
curl_close($curl);
Il risultato è:
Codice:
37.187.172.80
