POCO C++ library: connect to server with HTTPS or HTTP

I am using the POCO::Net::HTTPClientSession class to connect to the web server on IoT devices. I now need to support HTTPS to the device, but whether its HTTP or HTTPS is a configurable parameter in the device profile that may change at runtime.

I can connect just fine on HTTPS using the HTTPSClientSession class, and I can obviously connect on HTTP using the HTTPClientSession class. But I rather not use two objects for the two protocols. It seems I should be able to use the HTTPSClientSession object for both, since class HTTPSClientSession is a subclass of HTTPClientSession.

When I attempt to use an HTTPSClientSession object to talk to a plain HTTP server listening on port 80, The HTTPClientSession::sendRequest method throws exception Poco::Net::NetException with the message:

140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Is it appropriate to be trying to use the HTTPSClientSession object for HTTP? If so, what do I need to do?

I think you can't use HTTPSClientSession for HTTP communication. But you can make use of the fact that HTTPSClientSession is a subclass of HTTPClientSession:

std::shared_ptr<HTTPClientSession> session;
if(https) {
  session.reset(new HTTPSClientSession());
}
else {
  session.reset(new HTTPClientSession());
}
