CGI Scripts

Common Gateway Interface (CGI) scripts were the first method for creating dynamic web content, allowing web servers to execute programs and return generated content to browsers instead of serving static HTML files. CGI established the foundation for all server-side web programming by defining how web servers communicate with external programs to process form data, database queries, and user interactions.

Why CGI Scripts Matters

CGI scripts enabled the first interactive websites, online shopping, search engines, and user-generated content, transforming the web from a read-only medium into an interactive platform. Every modern web application traces its technical lineage back to CGI, which solved the fundamental problem of how to make websites respond dynamically to user input and database information.
