What is a cookie?
A cookie (sometimes known as web cookie, browser cookie or html cookie) is a small amount of data (<4Kb) that is sent to your computer or web-enabled device (hereafter referred to as a “device”) browser from a website’s server. The cookie can include a unique identifier within it.
Where does the cookie go?
The cookie is stored on your device’s hard drive (this is often called “setting a cookie”). Each website that wishes to send you its cookie can only do so if your device’s web browser preferences, that you can set personally, are set to allow this. To protect your privacy your device browser only permits a website to access the cookies it has sent to you, not the cookies sent to you by other websites. Many websites set one or more cookies to track online traffic through their website.
Wellcome Trust Sanger Institute-hosted websites, set cookies to store information about your:
- online preferences that allow us to tailor our websites to your data requirements
- access rights i.e. your ability to login to restricted services and the duration of that login
- Anonymous user tracking across our sites.
Users can set their device browsers to accept all cookies, to notify them when a cookie is issued, or not to receive cookies at any time. The last of these means that certain personalised features cannot then be provided to that user and accordingly they may not be able to take full advantage of all of the website’s features. Each browser is different, so check the “Help” menu of your browser to learn how to change your cookie preferences.
During the course of any visit to a Wellcome Trust Sanger Institute-hosted website, the pages you see, along with a cookie, are downloaded to your device. This enables our website publishers to find out whether the device (and its user) has visited the website before. This is done on repeat visits by checking to see, and finding, the cookie left there on the last visit.
There are three main uses:-
- Information supplied by cookies helps us to anonymously analyse the access patterns of visitors and helps us provide a better user experience.
- Web site usage. Our research funding agencies require annual reports to determine how often websites are visited by both academic and lay visitors.
- State information e.g. authentication or information about the user session.
