Read an external xml with hidden ID
===

I want to read some xml from a site, but they dont let me read only 500 xml/ day . So i have max 500 times to request their server. If i do that i get an error and say that i cant do that operation today from my domain. So i wonder if there is a way to request their server wihout letting them know from where you do that, some secret data i mean.

The function i use: 

$data = $this->getXMLfromURL('http://www.here_is_the_site_name.com/api/blogs?blog=http://here_is_the_site_that_i_request_data.com');

public function getXMLfromURL($url) {
        $Proxy = getenv("HTTP_PROXY");

        if (strlen($Proxy) > 1) {
            $r_default_context = stream_context_get_default ( array
                ('http' => array(
                    'proxy' => $Proxy,
                    'request_fulluri' => True,
                                ),
                )
            );
            
            libxml_set_streams_context($r_default_context);
        }
      
        $daten = simplexml_load_file($url);
      
        return ($daten);
    }
