About cookies

Most websites you visit use cookies in order to improve your user experience, by enabling websites to ‘remember’ you, either for the duration of your visit (using a ‘session cookie’) or for repeated visits (using a ‘persistent cookie’).

Cookies perform many different functions, like allowing you to navigate through pages efficiently, storing your preferences, and generally improving your experience of the website. Cookies make the interaction between you and the website faster and easier. If a website does not use cookies, it will “think” you are a new visitor every time you move to a new page of the site – for example, when you enter your login details and move to another page, it will not recognize you and will not be able to keep you logged in.

Some websites will also use cookies to enable them to target their advertising or marketing messages based, for example, on your location and/or browsing habits. Cookies may be set by the website you are visiting (‘first party cookies’) or they may be set by other websites that run contents on the page you are viewing (‘third party cookies’).

What is in a cookie?

A cookie is a simple text file stored on your computer or mobile device by the server of a website and only that server will be able to retrieve or read the content of that cookie. Each cookie is unique to your web browser. It will contain some anonymous information such as a unique identifier and the site name and some digits and numbers. It allows a website to remember things like your preferences or what is in your shopping cart.

What to do if you don’t want cookies to be set

Some people find the idea of a website storing information on their computer or mobile device a bit intrusive, particularly when this information is stored and used by a third party without them knowing. Although this is generally quite harmless, without allowing cookies you would not be able, for example, to see advertising that has been targeted to your interests. If you prefer, it is possible to block some or all cookies, or even to delete cookies that have already been set; but you need to be aware that you might lose some functions of that website.
