How to generate a valid http request in qt?

Question

API

Wherever I send a request through QT, the first line of the request gets host, which is then duplicated below as a header. It always seemed to me that this should not be and the host is prescribed separately. Is it legal at all? Will this always work correctly? How to fix it?

Answer 1

RFCs :
Translated into Russian: yes, the absolute path (with the host) in the Request-URI is allowed. And the Host header is required anyway.

Answer 2

Everything is good.
