    Access-Control-Request-Method

    The Access-Control-Request-Method request header is used when issuing a preflight request to let the server know which HTTP method will be used when the actual request is made. This header is necessary as the preflight request is always an OPTIONS and doesn't use the same method as the actual request.

    Header type Request header
    Forbidden header name yes
