What are cookies?
Each website can send its own cookie to your browser if your browser’s preferences allow it, but (to protect your privacy) your browser only permits a website to access the cookies it has already sent to you, not the cookies sent to you by other sites. You can configure your browser to accept all cookies, reject all cookies, or notify you when a cookie is set.
What cookies are being stored from this website?
tempCookieTest – 1 day from set This cookie is to determine if cookies have been enabled in the browser. If this cookie is unable to be stored, this suggests the user has made the decision to stop cookies so the notification bar is prevented from displaying.
stopAllCookies – 3 months from set This cookie is to prevent any new cookies from being stored.
This allows the website to track anonymous data regarding what, when and how pages are accessed which is used to make enhancements to the website to improve user experience.
__utma – 2 years from set/update. 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.
__utmb – 30 minutes from set/update. 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.
__utmc – Not set. 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.
__utmz – 6 months from set/update. 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.
__utmv – 2 years from set/update. The __utmv cookie passes the information provided via the _setVar() method, which you use to create a custom user segment. This string is then passed to the Analytics servers in the GIF request URL via the utmcc parameter. This cookie is only written if the _setVar() method has been added for the tracking code on your website page.
