WordPress "Expect" header fix
* By default, cURL sends the "Expect" header all the time which severely impacts
* performance. Instead, we'll send it if the body is larger than 1 mb like
* Guzzle does.
function add_expect_header(array $arguments)
$arguments['headers']['expect'] = !empty($arguments['body']) && strlen($arguments['body']) > 1048576 ? '100-Continue' : '';
return $arguments;
add_filter('http_request_args', 'add_expect_header');
