lives the actual Fast CGI engine in your server. I do not know what FCGI does when there is no such engine in the server. Anything between degrading gracefully to the "normal" CGI protocol and crashing loudly is possible.
Ask your sysadmin if he has mod_fastcgi (when your server is Apache) active in your (virtual) server.
A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
