A cookie consists of information sent by a web server to a web browser, and stored by the browser. The information is then sent back to the server each time the browser requests a page from the server. This enables the web server to identify and track the web browser.
We use both “session” cookies and “persistent” cookies on the website. We will use the session cookies to transfer information between pages whilst you navigate the website. We use the persistent cookies to remember your display preferences.
Session cookies will be deleted from your computer when you close your browser. Persistent cookies will remain stored on your computer until deleted, or until they reach a specified expiry date.
Most browsers allow you to refuse to accept cookies. This will, however, have a negative impact upon the usability of many websites, including this one.
