The include command inserts a file into the parsed file. You can nest files by including another parsed file, which then includes another file, and so on. The client requesting the parsed document must also have access to the included file if your server uses access control for the directories in which they reside.
In Sun Java System Web Server 6.1, you can use the include command with the virtual attribute to include a CGI program file. You must also use an exec command to execute the CGI program.
