Cookies are small pieces of data, stored in text files, that are stored on your computer or other devices when websites are loaded in a browser. They are widely used to remember you and your preferences, either for a single visit (through a session cookie) or for multiple repeat visits (using a persistent cookie). They ensure a consistent and efficient experience for visitors and perform essential functions, such as allowing users to register and remain logged in.
Cookies may be set by the site that you are visiting (known as first party cookies), or by other websites who serve up content on that site (third party cookies).
Cookies set by GlobalCluster
Cookies are used by GlobalCluster in a variety of ways. The cookies set will depend on the specific features that are enabled on a site. The cookies are only set when a user interacts with one of these features, or to allow admin functions to be performed from within the site’s dashboard.
