A cookie is a file containing an identifier (consisting of a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. This identifier is then sent back to the server each time the browser requests a page from the server.
Cookies can be used by web servers to identity and track users (visitors to a website) as they navigate different pages on the website and also to identify users returning to the website.
Cookies may be either “persistent” cookies or “session” cookies. A persistent cookie consists of a text file sent by a web server to a web browser, which is stored by the browser and remains valid until a set expiry date (unless it is deleted by the user before the expiry date). In contrast, a session cookie expires at the end of the user session when the web browser is closed.
We use both session cookies and persistent cookies on this website. We may send you the following cookies:
