$proxy_auth = 'https://SECRET:';

curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
curl_setopt($ch, CURLOPT_PROXYUSERPWD, $proxy_auth);
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_TIMEOUT, 180);
curl_setopt($ch, CURLOPT_CAINFO, '/var/www/html/.docker/certificate/zyte-proxy-ca.crt'); // required for HTTPS
