It seems that QNetworkCookie:: parseCookies only parses cookies from a server http response,
with a "Set-Cookie" header.
Qt offers no way to parse cookies from the "Cookie" header inside a client http request.
This is weird because, Qt provides a function to build http cookies as server or as client with the function QNetworkCookie::toRawForm. Indeed there is a "form" parameter letting us choose between server/client format.
But there is no such thing for QNetworkCookie:: parseCookies.
