It's one handler, not complete fcgi server. Apache and other web servers have solutions to spawn pool of FCGI processes and serve them requests. RT 3.8 has bin/fastcgi_server that is actually an external fcgi server you can use with nginx without additional spawner. For 4.0 you can use RT-Extension-Nginx. You can use this as a reference to setup 3.8. > Detail: > > It is a site standard that web apps must be fronted by nginx and run as > a FastCGI process on a socket.
