What is FastCGI in HTML?
FastCGI is a way to have CGI scripts execute time-consuming code (like opening a database) only once, rather than every time the script is loaded. In technical terms, FastCGI is a language-independent, scalable, open extension to CGI that provides high performance without the limitations of server-specific APIs.
How fast does CGI work?
