A cookie is a text file which a web site saves on a user’s computer after the user visits the site. The cookie is stored by the user’s browser in a location reserved for cookies.
A cookie saves information about the user’s visit to the web site. This information can include the user’s preferences regarding web site appearance and behavior, based on the user’s actions at that site. Cookies can also keep track of the number of visitors visiting each page at a site.
There are two main types of cookie:
Session Cookies: A session cookie is only saved for as the duration of the user’s visit to the web site. It tracks the user’s behavior during the visit, and is then deleted.
Persistent Cookies: A persistent cookie has an expiration date or lifespan, which is stored as part of the cookie data. It expires when that date is reached or at the end of the lifespan. Persistent cookies can be used to store such things as user login information (to keep the user logged in at each visit), and to send information about the user’s browsing activity to the web site or to advertisers.
There may be times when a visitor is not willing to allow cookies. This can happen, for example, if the visitor is using a computer that is public (at a library, school, or Internet cafe, for example), or that otherwise cannot be trusted or does not allow control of security. It is possible to instruct most browsers to not save cookies. When a user does this, however, web sites may not operate as it was designed to, and the user will be required to enter basic information for each visit. If a machine is secure and can be trusted (a personal laptop or a desktop system at home, for example), it is advisable to allow cookies in order to allow the site to function properly and provide a high-quality user experience. All visitors have the option to reject the consent of cookies at any time by exiting our website and delete the cookies from their browser.
