4.4.1 CGI program definition

There are three ways to execute CGI programs:

Specify a directory containing CGI programs in the ScriptAlias directive.
Specify the cgi-script handler in the file extension by using the AddHandler directive.
Specify the cgi-script handler in the SetHandler directive.

Hitachi recommends you to set the ScriptAlias directive in httpsd.conf for easy management of CGI programs.
