Adding Actions to the Dispatcher
Go Up to The Web Dispatcher
Open the action editor from the Object Inspector by clicking the ellipsis on the Actions property of the dispatcher. Action items can be added to the dispatcher by clicking the Add button in the action editor.
Add actions to the dispatcher to respond to different request methods or target URIs. You can set up your action items in a variety of ways. You can start with action items that preprocess requests, and end with a default action that checks whether the response is complete and either sends the response or returns an error code. Or, you can add a separate action item for every type of request, where each action item completely handles the request.
