Manage Events - Session Attributes tab
A session attribute is a pre-defined variable that is persistent throughout the life of a Discover session. Session attributes may be used to store various data that may be referenced by events at any point during the session.
- A user-created session attribute may be populated by the output of multiple events.
There are two types of session attributes:
- System Session Attributes: Discover provides a set of session attributes
that are automatically tabulated and updated by the Discover Canister. These attributes are available
for use in generating events through the Discover Event Manager.
- For more information about system session attributes, see "How session attributes are populated by the system" in the Unica Discover Event Manager Manual.
- User-Defined Session Attributes: Through the Event
Manager, you may create up to 64 session attributes for tracking session
data specific to your web application. Note: Write access to user-defined session attributes is permitted only through the defined action of an event.
- Session attribute values are strings with a maximum length of 255 characters.
- Session attributes are indexed automatically.
You assign and reassign values to session attributes through events.
