Third-party cookies and Personalization
Personalization creates first-party cookies by default, using the domain
of the website the visitor is viewing. Third-party cookies are optional in
Personalization, and if enabled, use the acquia.com domain.
Third-party cookies are useful if you maintain several websites using
different domain names, and want to track users across all your domains. Some
browsers may prevent the creation of third-party cookies or limit their life
span. For example, browsers using Webkit’s Intelligent Tracking Prevention,
such as Safari, will delete cookies and browsing data if a website visitor has
not interacted with your website in 30 days.
