👉 CGI, or Common Gateway Interface, is a software technique that allows web servers to execute dynamic content on the fly using server-side scripts. It acts as a bridge between the web server and client-side scripts, typically written in languages like PHP, Perl, or Python, and enables the server to generate and send dynamic HTML pages to web browsers. When a user requests a page, the web server receives the request, processes it with a CGI script, and sends back a customized HTML response. This separation of concerns allows for more flexible and dynamic web applications, as the server-side logic can be developed independently of the front-end presentation layer, enhancing scalability and maintainability.
