The code form an example of curl_exec that executes simple get request, send it twice to my simple script <?php echo json_encode(["error" => 0]); file_put_contents(__DIR__ . '/log.txt',print_r(getallheaders(),true)."\n\n",FILE_APPEND); ?> The file "log.txt" shows multiple requests! ``` Array ( [Host] => domain.com [X-Forwarded-For] => xxx.xxx.xxx.xxx [Connection] => close [Accept] => */* ) Array ( [Host] => domain.com [X-Forwarded-For] => xxx.xxx.xxx.xxx [Connection] => close [Accept] => */* ) ``` How to send only one request?????
