1.2 Cookies

In order to facilitate tracking of session and visitor activities, IBM® Digital Analytics makes use of 'Session' cookies and 'Visitor' cookies.

• Session Cookie: The 'Session' cookie exists only for the lifetime of the current browser session. The Session cookie exists from the point at which the first tag is received from the website until 1) the visitor closes all browser windows for the browser in question or 2) more than 30 minutes pass without receiving a data collection tag from the browser session. One or more 'sessions' might be associated with a 'visitor'.
• Visitor Cookie: The 'Visitor' cookie persists after the visitor closes all browser windows. The 'Visitor' cookie contains a cookie ID referenced by IBM Digital Analytics to identify a visitor returning to the site across multiple 'sessions'.

In addition to the 'Visitor' and 'Session' cookies, several additional session-based cookies might be set depending on your specific implementation and IBM Digital Analytics version. Certain optional IBM Digital Analytics applications might set additional session cookies ( IBM Content Recommendations, IBM AdTarget and others). See 6.3 Client-managed first-party cookie migration for more details.
