superPort is a special feature of the Illusory platform.
By default, all proxies come with unique ports for both HTTP & SOCKS5 protocols.
With superPort, you can forward all HTTP & SOCKS5 requests through any proxy you specify, without having to change the proxy details in your application.
Forwarding requests via superPort to the specified proxy
This allows you to set the superPort as your proxy within your application, but forward the requests through any of your proxies.
