FastCGI (Fast Common Gateway Interface) is a protocol used for communication between web servers and dynamic content generation applications, such as PHP, Python, Ruby, and others. It is an improvement over the original CGI (Common Gateway Interface) protocol, which had performance issues when dealing with dynamic content.
FastCGI creates a persistent connection between the web server and the application, allowing multiple requests to be processed by the same instance of the application, which reduces the overhead of starting and stopping the application for each request. This results in faster and more efficient handling of dynamic content, which is especially useful for high-traffic websites.
FastCGI is supported by most popular web servers, including Apache, Nginx, and Lighttpd, and is widely used in the web development industry. It is a standard feature in popular web hosting control panels, such as cPanel and Plesk.
