Generic-CGI Server Class
The generic-CGI execution environment has the following characteristics and
constraints:
•
You can run as many simultaneous CGI processes as there are processes in the
generic-CGI server class.
•
The .cgi programs are launched in the same processor in which the generic-CGI
server is running.
•
As in standard CGI, a new process is created for each invocation.
Generic-CGI is the best choice for running an existing .cgi program or a program that
will run without change in various WebServer environments. For high-volume
applications, you can achieve better performance by using Pathway CGI, as described
next.
