ci_session

Cookie normally associated with the Codelgniter framework for building PHP based applications. Usually used to maintain a user state during a browser session for consistency of user experience. By default the cookie is destroyed when the browser session ends, in which case it can be Essential. However, it can optionally be stored in a database and be used for tracking users for other purposes and in such cases a category of Essential will probably not apply.

_utmb

This is one of the four main cookies set by the Google Analytics service which enables website owners to track visitor behaviour and measure site performance. This cookie determines new sessions and visits and expires after 30 minutes. The cookie is updated every time data is sent to Google Analytics. Any activity by a user within the 30 minute life span will count as a single visit, even if the user leaves and then returns to the site. A return after 30 minutes will count as a new visit, but a returning visitor.

_utmc

This is one of the four main cookies set by the Google Analytics service which enables website owners to track visitor behaviour and measure site performance. It is not used in most sites but is set to enable interoperability within the older version of Google Analytics code known as Urchin. In this older version this was used in combination with the _utmb cookie to identify new sessions/visits for returning visitors. When used by Google Analytics this is always a Session cookie which is destroyed when the user closes their browser. Where it is seen as a Persistent cookie it is therefore likely to be a different technology setting the cookie.
