A cookie is a file containing an identifier (a string of letters and numbers) that is sent by a web server to a web browser and is stored by the browser. The identifier is then sent back to the server each time the browser requests a page from the server.
- identify users
- remember users’ custom preferences
- help users complete tasks without having to re‑enter information when browsing from one page to another or when visiting the site later.
Cookies can also be used for online behavioural target advertising and to show adverts relevant to something that the user searched for in the past.
How are they used
What are the different types of cookies:
A cookie can be classified by its lifespan and the domain to which it belongs. By lifespan, a cookie is either a:
- session cookie which is erased when the user closes the browser
- persistent cookie which remains on the user’s computer/device for a pre-defined period of time.
As for the domain to which it belongs, there are either:
- first-party cookies which are set by the web server of the visited page and share the same domain, such as Google Analytics;
- third-party cookies stored by a different domain to the visited page’s domain, such as Google Analytics.
What type of cookies do we use?
Here are some examples of the main cookies on our site, what they do and how you can alter your settings to stop cookies.
The __cfduid cookie provided by the Company Cloudflare, it is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis. For example, if the visitor is in a coffee shop where there are a bunch of infected machines, but the specific visitor’s machine is trusted (e.g. because they’ve completed a challenge within your Challenge Passage period), the cookie allows us to identify that client and not challenge them again. It does not correspond to any user ID in your web application, and does not store any personally identifiable information.
The _ga cookie name is asssociated with Google Universal Analytics – which is a significant update to Google’s more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.
The _gid cookie name is asssociated with Google Universal Analytics. This appears to be a new cookie and as of Spring 2017 no information is available from Google. It appears to store and update a unique value for each page visited.
The main purpose of this cookie is: Performance
The _gat cookie name is associated with Google Universal Analytics, according to documentation it is used to throttle the request rate – limiting the collection of data on high traffic sites. It expires after 10 minutes.
