Information about our use of cookies
This website uses three types of cookies: Strictly Necessary, Preferences and Statistics cookies. We use cookies on this website to help us understand better how our visitors use and interact with our website so we can make improvements to the user experience.  Some cookies are also essential for the website to work.
Strictly Necessary cookies
Strictly Necessary cookies help make a website usable by enabling basic functions like page navigation and access to secure areas of the website. The website cannot function properly without these cookies. Please see below a list of all the Strictly Necessary cookies we use on our website:
Cookie name Cookie description Type Expiry Provider
WebAnalyticsSessionId2 A feature of the ASP.NET platform search facility, set after submitting a search of the site and its content HTTP Session
BCSI-CS-xxxxxxxxxxx This cookie name is associated with proxy server technology from Bluecoat. Its pattern starts with BCSI-CS- followed by an alpa numeric string. It is generally not actually set by the website being visited, but as a result of accessing the site through a network (like a company network) using Bluecoat technology. Its appearance therefore is not a function of the website found on, but only appears in Cookiepedia when someone has used our Collector plug-in from a Bluecoat enabled network. HTTP Session
cc_cookie_accept Cookie that remembers that you allowed cookies HTTP 1 year
Statistics cookies
Statistic cookies help website owners to understand how visitors interact with websites by collecting and reporting information anonymously. Please see below a list of all the Statistics cookies we use on our website:

_utmb This works with _utmc to calculate the average length of time you spend on our website. Used to determine new sessions/visits.

__utmc It is not used in most sites but is set to enable interoperability with the older version of Google Analytics code known as Urchin. In this older versions this was used in combination with the __utmb cookie to identify new sessions/visits for returning visitors.

Where it is seen as a Persistent cookie it is therefore likely to be a different technology setting the cookie. HTTP Session
