Your consent to this website using cookies
In the production of this website cookies (http://www.allaboutcookies.org/) are used to store anonymised data on the pages visited by all users. The cookies used are set using Google Analytics and our website content management system. These package provides a series of reports detailing tracking data such as most visited pages, time spent on the website and total number of daily visitors.
Cookies we use:
ibrscbox - is used to ensure users do not see an overlay promoting forthcoming events more than once.
ibrscsmall - is used to ensure users do not see an events modal box promoting forthcomming events more than once.
The cookies named __utma through __utmz and __ga to __gat come from Google Analytics, which primarily uses it to track visits. The cookie names likely come from the earlier versions called the Urchin Tracking Module, and are also by the newer ga.js.
__utmz stores where a visitor came from (search engine, search keyword, link)
__utma stores each user's amount of visits, and the time of the first visit, the previous visit, and the current visit (presumably partly for double checking of this information).
__utmb and __utmc are used to check approximately how long you stay on a site: when a visit starts, and approximately ends (c expires quickly). If you look at cookie state changes (e.g. using firecookie), you will see these change regularly.
__ga is used to distinguish users.
__gid is used to distinguish users.
__gat1 is used to throttle request rate.
__utmv is used for user-custom variables in Analytics
__utmk - digest hashes of utm values (verify)
__utmx is used by Website Optimizer, when it is being used(verify)
