Depending on your browser's security settings, websites may be allowed to create and store small files called 'cookies' in a specific directory on your computer to help with the functionality of the site. Cookies cannot harm your computer in any way. Only the website that created the cookie can subsequently reuse it.

There are two types of cookies:

  • A persistent cookie remains on your computer for a period of time to allow a website to recognise you when you return and present you with the appropriate customised pages
  • Session-specific cookies are deleted when you shut down your browser. These are used on sites where you log in; the cookie ensures that you stay logged in throughout that visit.

Currently, we do maintain site logs which include the IP address details of all machines accessing our pages. This enables us to monitor website usage to see:

  • Which pages are the most popular
  • Which pages are hardly used or never visited
  • How much our site is used

Any IP information is treated as strictly confidential and is not published or given out to any third party.

Cookies for measuring site usage
