Cookies

Our website uses different types of cookies. A cookie is a small file of letters and numbers that we put on your computer if you agree. These cookies allow us to distinguish you from other users of the website which helps us to provide you with a good experience when you browse our website and also allows us to improve our site.

The cookies we use are ‘analytical’ cookies. They allow us to recognise and count the number of visitors and to see how visitors move around the site when they’re using it. This helps us to improve the way our website works, for example by making sure users are finding what they need easily. Read more about the individual analytical cookies we use and how to recognise them here.

Cookie Purpose
_utma 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 __utmacookie 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.
_utmb 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 ona page on your site for longer than 30 minutes. You can modify the default length of a user session with the_setSessionCookieTimeout() method.
_utmc 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.
_utmz 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.
mailbox_uid Upon login, this cookie stores an authenticated users internal id in an encrypted format. If a user navigates away from the website or indeed closes their browser, upon return, they will not be required to re-authenticate with the site. The cookie is valid for a period of 14 days, after which they will be required to sign in again.
mailbox_uidc This cookie is used in conjunction with mailbox_uidc to validate its authenticity. It is a hashed string of the mailbox_uid cookie against a secret salt. This is updated when the mailbox_uid is renewed.
