> [`WinHttpSetTimeouts`](https://learn.microsoft.com/en-us/windows/win32/api/winhttp/nf-winhttp-winhttpsettimeouts) describes `nReceiveTimeout` as the time "to receive a response to a request". However the wait for response headers in `WinHttpReceiveResponse` is actually governed by [`WINHTTP_OPTION_RECEIVE_RESPONSE_TIMEOUT`](https://learn.microsoft.com/en-us/windows/win32/winhttp/option-flags#winhttp_option_receive_response_timeout).

Yea basically this should be documented there.
