thanks. Was looking for a simple demo showing the setting of headers using POCO. Clear enough!

Can headers be set when using httpstreamfactory?

Thank you

Exactly what I was looking for, thanks!

Please check my question at below link and help

very helpful, thanks! Remember if its an HTTPS session you will need to use HTTPSClientSession session(uri.getHost(), uri.getPort());
and initialize SSL.

Thanks, man. You helped me a lot.
