Define application behaviors

Application behaviors define actions taken when an event occurs such as sign in, sign out, or in the case of an error.
During this task you will define one or more custom behaviors to specify how an application should behave on sign in, sign out, error, lack or a session or session expired and in similar situations.

To add a behavior:

  1. Navigate to Access Gateway Admin UI console.

  2. From the Topology tab or the Applications tab, open the application.
  3. In the Settings pane, expand Behaviors.

Choose one of the following custom behaviors:

Login

Fields:

Field Description
Login Drop-down list box, behavior on login.
Login path Path to login endpoint URL.
Relative or fully qualified depending on use.
Executed after successful login.

URL must be unique across Login, Logout, and Error behaviors. Access Gateway does not support using the same URL for multiple behaviors. Also note that URL cannot overlap with existing defined policy. See Manage application policy.
