This avoid the problem when several requests are sent using the same connection and those are processed sequentially. ...

Indy supports RSA and EC Certificates when using the openSSL libraries, but by default, the EC certificates can be created different curves and the openSSL libraries only are configured with some of these curves. So if you're using an EC Certificate that it's not included by the default by the openSSL libraries, the certificate won't work...

Azure IoT allows to send data using several protocols like MQTT or AMQP, but in some cases, the size of the message is too big and requires to upload files to Azure Servers.
