It looks like Qhttp::request(const QHttpRequestHeader &header, QIODevice *data, QIODevice *to)
method does not send request parameters for GET request.

Method Qhttp::request(header,data ...) sends a request type defined in header.
And this can be POST,GET etc.

Qhttp::request(header,data ...) should send request parameters as data variable. It is OK for POST.
But it does not send it for GET

I do not want to use Qhttp::get() method because I need to send a special defined request header to server.
