Like many other websites, (the “Website”) uses ‘cookies’ – a text-only string of information that passes to your computer’s hard disk through your web browser so that the Website can remember who you are. Cookies cannot be used by themselves to identify you although they may be used to identify your IP address.
We use these to understand more about what our visitors are looking for: in particular which resources are most popular, which resources are least popular, and how people find us.

We use two types of cookies on our Website: 1) per session cookies, which are temporary cookies that remain in the cookies file of your browser until you leave the Website; 2) persistent cookies, which remain in the cookies file of your browser for longer (dependent of the lifetime of the specific cookie). These cookies are used to store information between visits to a site, so that we can tell whether you are coming to our site for the first time, or whether you visit frequently.
If you do not wish to receive cookies you can easily modify your web browser to refuse cookies or to notify you when you receive a new cookie.
