Cookies Policy


Our website uses cookies to distinguish you from other users of our website. This helps us to provide you with a good experience when you browse our website and also allows us to improve our site. By continuing to browse the site, you are agreeing to our use of cookies.

IP addresses

We collect visitor information by using cookies and pixel tags and when you use the sharing icons (provided by Share This) to share content from our website or access other websites which collect statistical data about our users’ browsing actions and patterns but does not identify any individual.


Our website only uses cookies required by Google Analytics and a session cookie set by the ASP.NET web framework.  Both of these technologies and what a cookie actually does, is explained below.

A cookie is a parcel of text sent back and forth between a web browser and the server it accesses to collect data about a given browser, along with the information requested and sent by the browser’s operator (the visitor).

Google Analytics is a widely-used web analytics service provided by Google, Inc to generate statistics about visitors to websites. Google stores the information collected by its cookies on servers in the United States. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google’s behalf. Google will not associate your IP address with any other information held by Google. By using our website, you consent to the processing of information by Google in the manner and for the purposes set out above.

ASP.NET is a free web framework from Microsoft for building web sites and web applications.  ASP.NET must track a session ID for each user so that it can map the user to session state information on the server.  By default and on our website, ASP.NET uses a non-persistent cookie to store the session state. However, if a user has disabled cookies on the browser, session state information cannot be stored in a cookie.

The following Google Analytics and ASP.NET cookies are used on our website:

_utmaThis cookie is typically written to your browser upon your first visit to our website from that web browser. If you delete the cookie and you subsequently visit our website a new _utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to our website and it is updated with each page view. It 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.2 years from set/update
_utmbThis cookie is used to establish and continue a user session with our website. When you view a page on our website, 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 you visit a different page on our website, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as your activity continues within 30-minute intervals. This cookie expires when you pause on a page on our website for longer than 20 minutes.30 minutes from set/update
_utmcThis 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.Not set
_utmzThis cookie stores the type of referral used by you to reach our website, whether via a direct method, a referring link, a website search or a campaign such as an email link. It is used to calculate search engine traffic, campaigns and page navigation within our website. The cookie is updated with each page view to our website.6 months from set/update
