Our website uses third party 'cookies'.
A cookie is a small file, typically of letters and numbers, downloaded on to a device when a user accesses certain websites. Cookies are then sent back to originating website on each subsequent visit. Cookies are useful because they allow a website to recognise a user's device.
We use third party traffic log cookies to identify which pages are being used. This helps us analyse data about webpage traffic and improve our website. We only use this information for statistical analysis purposes.
A cookie in no way gives us access to your computer or any information about you, other than the data you choose to share with us.
The following is a list of third party cookies used by our website, and what they are used for:
|__utma||This cookie is typically written to the browser upon the first visit to our site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits our site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to our site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure.|
|__utmb||This cookie is used to establish and continue a user session with our site. When a user views a page on our site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on our site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. This cookie expires when a user pauses on a page on our site for longer than 30 minutes. You can modify the default length of a user session with the _setSessionCookieTimeout() method.|
|__utmc||This cookie is no longer used by the ga.js tracking code to determine session status.|
Historically, this cookie operated in conjunction with the __utmb cookie to determine whether or not to establish a new session for the user. For backwards compatibility purposes with sites still using the urchin.js tracking code, this cookie will continue to be written and will expire when the user exits the browser. However, if you are debugging our site tracking and you use the ga.js tracking code, you should not interpret the existence of this cookie in relation to a new or expired session.
|__utmz||This cookie stores the type of referral used by the visitor to reach our site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within our site. The cookie is updated with each page view to our site.|
If you do not wish to accept cookies through your web browser, you can go into your settings and change these. However, this may prevent you from taking full advantage of the website.
