User Interface
A user interacts with Polyglot. Polyglot works internally with software servers. By default Polyglot runs on port 8184, Softwareserver on port 8182. A user can use "http://<polyglot_ip>:8184/" to see the available endpoints / URLs, such as "http://<polyglot_ip>:8184/servers" to see the server IP list, or "http://<polyglot_ip>:8184/form" to use a form to submit a conversion request.
