What are cookies?
A cookie is a file containing an identifier that is sent by a web server to a web browser and stored by the browser when you access a website. A browser is the program you use to access a website (Firefox, Internet Explorer, Safari for example). The identifier is then sent back to the server each time the browser requests a web page from the server.
Cookies can be used by web servers to identity and track users as they navigate to different pages on a website. These are called session cookies and they expire after a browser session (when browser is closed). They are not stored long-term. Cookies can also be used to identify users returning to a website. These are called persistent (tracking) cookies and they are stored between browser sessions. They are useful for example to remember user preferences or to target advertising in a later session.
Session and persistent cookies may be set by the website itself (first-party cookies) or by a third party operating through that website (Google Analytics for example). In any case, you can check client-side cookies easily using the Firefox browser (example for Firefox, version 15.0.1). For this purpose select from menu Tools/Page Info/Security/View Cookies. You can then see a list of all the cookies installed by the website.
