Access-Control-Request-Method
The HTTP Access-Control-Request-Method request header is used by browsers 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 because the preflight request is always an OPTIONS and doesn't use the same method as the actual request.
| Header type | Request header |

| Forbidden request header | Yes |
