Whats the difference between the CGI and the FastCGI interfaces?
Starting from version 2.3, Abyss Web Server features support for applications and interpreters conforming to the FastCGI specification. A FastCGI application or interpreter is loaded when needed by the web server, it executes a script, and sends its output back to the server. But instead of having its process automatically unloaded from the system as with CGI, it remains in sleeping state waiting for another request from the web server. When the server needs it to process another script, it will simply send a request to the already loaded FastCGI process. This boosts significantly the performance as a FastCGI interpreter or application once loaded can process an unlimited number requests which saves the overhead of processes loading/unloading incurred with CGI.
