Cakephp Http Socket not responding as i assumes

#1

I am trying to fetch headers of Multiple domains and using CakephpHttpSocket but somehow not getting required Results
here is my code to hit a http socket call

private function justinsert($url)
	{
		// {
			$method='POST';
			$Pages = new PagesController;
					$data['Server']['link']=$url;
					$results=$Pages->callAPI($method, $url,'');
					$data['Server']['webservername']=$results->getHeader('server');
					$headersdata=$results->headers;
						debug($results);
					if(isset($headersdata['X-Hostname']))
					{

					$data['Server']['php version name']=$headersdata['X-Powered-By'];
						$data['Server']['X-Hostname']=$headersdata['X-Hostname'];
					}
					elseif(isset($headersdata['Location'])){
					$data['Server']['php version name']=$headersdata['X-Powered-By'];

						$data['Server']['X-Hostname']=$headersdata['Location'];
					}
					else{
					$data['Server']['php version name']=$headersdata['X-Powered-By'];

						$data['Server']['X-Hostname']=$headersdata['Last-Modified'];
					}

					
					$this->Server->create();
					if($this->Server->save($data))
					{
						debug($data);
					}
					unset($data);
					unset($results);
				// }

	}

and here is the code for Final hit to Http Socket

    public function callAPI($method, $url, $data){

    	$HttpSocket = new HttpSocket();
    	$data = json_encode($data);
    	$request = array(
    		'header' => array('Content-Type' => 'application/json',
    	),
    	);



    	$results = $HttpSocket->post($url, $data,$request);

    	return $results;
    }

issue is that i am getting same header for almost all calls. Is there is some issue with my call or http Socket connection makes some cache and fetching same results for all calls
