Cookies make your experience of using web sites faster and easier. They are not programs and cannot carry viruses or install malware on your computer. Cookies allow web sites to create a customised view of pages to which you navigate. For example, they are commonly used to authenticate or identify registered users of a website without requiring them to sign in each time they access it. Other uses include maintaining a ′shopping basket′ of goods a user has chosen to purchase, site personalisation (presenting different pages to different users) and tracking the pages a user has visited on a site for analysis purposes.
A cookie often includes a unique identifier, which is a randomly generated number. This is stored on your device′s hard drive. Many cookies are automatically deleted after you finish using a website.
Cookies may come with or without an expiry date. Cookies without an expiry date (session cookie) exist until the browser is closed, while cookies with an expiry date may be stored by the device until the expiry date passes.
You can restrict or block cookies set by NWL but this may limit your use of some functionality, such as filling in forms and getting access to password protected areas that are in use across any of the sites we manage. However, most things you do on our site will still be possible even with cookies disabled.
Cookies are sent to your browser (whether you use Internet Explorer, Google Chrome, Safari or any other browser) by a website and then stored in the cookies directory of your device.
