CGI

Modules

CGI::Application

• builds upon CGI adding a structure for writing truly reusable Web-applications
• "run-mode" - single screen of an application
• "Mode Parameter" is used to store (and retrieve) the current run-mode of your application
• maps each run-mode to a specific Perl subroutine ("Run-Mode Method") that implements the behavior of a single run-mode
• an "abstract class", and is only used via inheritance

package Your::Web::Application;
use base 'CGI::Application';

• setup() method defines a map between run-modes and run-mode methods
