Purpose

Examples
Description
Redirects the current action to another action, optionally passing parameters and/or errors. When issuing a redirect from a namespaced controller, the namespace for the target controller is implied to be that of the controller initiating the redirect. To issue a redirect from a namespaced controller to a controller that is not in a namespace, the namespace must be explicitly specified with a value of null as shown below.
class SomeController {
static namespace = 'someNamespace'
def index() {
// issue a redirect to PersonController which does not define a namespace
redirect action: 'list', controller: 'person', namespace: null
}
