🆚 CGI vs. DNS Prefetch

Common Gateway Interface (CGI) is an interface specification that enables web servers to execute an external program to process HTTP requests.

The rel="dns-prefetch" attribute on HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.

It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.
