We use these as sparingly as possible, there are only two cookies created by the Faculty-X and four by google analytics.
(Contains a PHP "session ID", expires when the browser is closed)
(Contains a PHP "session ID", can also contain an email address and encrypted password, expires after one year)
The "PHPSESSID" cookie is required so that the site can recognise the same user clicking from page to page. Without it, every page would be treated as the first visit to the site, and anything added to the shopping basket would be instantly forgotten. Online shopping would, therefore, be impossible.
The "session" cookie is intended for the user's convenience, Faculty-X creates this with a copy of the initial session ID so that they can be classed as "returning" and the contents of their shopping basket will still be available. If the user signs in with an email address and password, these login details are are also saved so that they can remain logged in when returning (the password is encrypted). If the user signs out, their login details are removed from the cookie.
A persistent cookie - remains on a computer, unless it expires or the cookie cache is cleared. It tracks visitors. Metrics associated with the Google __utma cookie include: first visit (unique visit), last visit (returning visit). This also includes Days and Visits to purchase calculations which afford ecommerce websites with data intelligence around purchasing sales funnels.
__utmb Cookie & __utmc Cookie
These cookies work in tandem to calculate visit length. Google __utmb cookie demarks the exact arrival time, then Google __utmc registers the precise exit time of the user.
Because __utmb counts entrance visits, it is a session cookie, and expires at the end of the session, e.g. when the user leaves the page. A timestamp of 30 minutes must pass before Google cookie __utmc expires. Given__utmc cannot tell if a browser or website session ends. Therefore, if no new page view is recorded in 30 minutes the cookie is expired.
Cookie __utmz monitors the HTTP Referrer and notes where a visitor arrived from, with the referrer siloed into type (Search engine (organic or cpc), direct, social and unaccounted). From the HTTP Referrer the __utmz Cookie also registers, what keyword generated the visit plus geolocation data.
