Airlock Gateway offers three different ways of session tracking.
- Select the tracking method depending on your client-side requirements:
- Session tracking with session cookie, which is suitable for most browser-based applications. See also the informative article Cookie handling and cookie types.
- Session tracking based on SSL session ID. For more information see below. In addition to the GUI-based configuration, the REST API allows to dynamically select cookie-based or SSL ID-based tracking mode.
- Session tracking via header session token. This is the recommended method for client applications without cookie stores, etc., and can be enabled in the Expert Settings.
