Стандарт Cross-Origin Resource Sharing работает с помощью добавления новых HTTP-заголовков, которые позволяют серверам описывать набор источников, которым разрешено читать информацию, запрашиваемую web-браузером. В частности, для методов HTTP-запросов, которые могут привести к побочным эффектам над данными сервера (в частности, для HTTP методов, отличных от GET или для POST запросов, использующих определнные MIME-типы), спецификация требует, чтобы браузеры "предпроверяли" запрос, запрашивая поддерживающие методы с сервера с помощью метода HTTP-запроса OPTIONS и затем, поверх "подтверждения" с сервера, отсылали фактический запрос с фактическим методом HTTP-запроса
