The WEB server sends CGI environment variables and standard input to the FastCGI subprocedure, php-cgi;php- CGI, and returns the standard output and error information to the WEB server. At this point, the php-cgi subprocedure closes the connection, the request closes, and then continues to wait and process the next request connection from the FastCGI process manager.
