This site uses small files called cookies to help customise your experience. The cookies we use cannot be used to identify you personally.
What are cookies?
Permanent cookies – cookies that are stored on your computer to track repeat visits and site navigation. They are primarily used to help speed up or enhance your experience of services or functions offered on the site.
Temporary cookies (or session cookies) – cookies which are deleted when you shut down your browser.
Websites typically use temporary cookies to ensure that you are recognised when you move from page to page within one site and that any information you have entered is remembered during that particular visit.
Disabling cookies may prevent users from using certain websites. If you would like to disable cookies, you can find out how at: www.allaboutcookies.org/manage-cookies
We use the following cookies on our site:
This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your 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.
This cookie is used to establish and continue a user session with your site. When a user views a page on your 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 your 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 your site for longer than 30 minutes. You can modify the default length of a user session with the _setSessionCookieTimeout() method.
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 your 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.
This cookie stores the type of referral used by the visitor to reach your 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 your own site. The cookie is updated with each page view to your site.
Expires: when user exits browser.
