The application has an internal proxy, that can be enabled/disabled from the configuration window, that serves all the requests directly, if no proxy is activated, or redirects the requests to the current active proxy, if any.

This internal proxy is useful for applications that don't support dynamic proxy configuration or that the application doesn't support yet to configure them. Is this cases, you can configure these applications to use this proxy (by default 127.0.0.1 on port 8123), and forget about the current proxy being used; the internal proxy will serve the requests according to the current running configuration.

Note: established connection when changing proxy will continue working with the previous configuration.
