Hi, I found there are some Ruby programs are running in this development machines. Now I need to add some functionality into the Ruby program, but I don't know where to look into its starting program or its main body of the program. in aparche/httpd.conf file: <IfDefine SSL> ## ## SSL Virtual Host Context ## FastCgiServer /www/apps/scripts/public/dispatch.fcgi -idle-timeout 90 -initial-env RAILS_ENV=production -processes 10 <VirtualHost _default_:443> Here is the dispatch.fcgi script: require File.dirname(__FILE__) + "/../config/environment" require 'fcgi_handler' RailsFCGIHandler.process! I got stuck. I don't know how does this dispatch.fcgi program invoke which ruby main program... Can anyone please shed some light on me? Thanks S
