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.
