About:
FastCGI (fcgi) is a binary protocol for interfacing interactive programs with a web server. It overcomes the limitations of CGI by keeping processes persistent, eliminating the overhead of process creation for each request. This results in significantly improved performance and scalability for dynamic web applications.

Key Features:

Persistent application processes to reduce overhead
High-performance binary protocol for web servers
Language and server agnostic implementation
Efficient handling of concurrent requests

Use Cases:

Accelerating dynamic content generation in web applications
Deploying scalable backend services behind web servers
Integrating C/C++ applications with web environments

Alternatives:

WSGI – Python-specific standard, whereas FastCGI is language-agnostic and protocol-based.
SCGI – Simpler protocol than FastCGI, but FastCGI has broader server and language support.
