Cookies are files sent by web servers to web browsers, and stored by the web browsers.
The information is then sent back to the server each time the browser requests a page from the
server. This enables a web server to identify and track web browsers.
There are two main kinds of cookies: session cookies and persistent cookies. Session cookies are
deleted from your computer when you close your browser, whereas persistent cookies remain
stored on your computer until deleted, or until they reach their expiry date.
Most browsers allow you to refuse or accept cookies. Please take a look at your browser settings
to control these. Blocking cookies will have a negative impact upon the usability of our website.
