When you request a URL with OkHttp, here's what it does:

 1. It uses the URL and configured OkHttpClient to create an **address**. This address specifies how we'll connect to the webserver.
 2. It attempts to retrieve a connection with that address from the **connection pool**.

        return ComponentUtil.getFessConfig().isRateLimitEnabled();
    }

In the DNS server(s) you would configure a record (an "`A record`") to point **your domain** to the public **IP address of your server**.

You would probably do this just once, the first time, when setting everything up.

/// tip

This Domain Name part is way before HTTPS, but as everything depends on the domain and the IP address, it's worth mentioning it here.
