Cookies are often used internally in a web browser to communicate with the web site but can also make navigating the site easier. For instance, they allow any settings or preferences to be saved so users do not have to make repeated entries. They also enable the gathering of visitor frequency statistics for different web sites.
There are two kinds of cookies:
- Session cookies, which are temporarily stored in the computer’s memory whilst the visitor uses a web site. Session cookies are erased when the browser is closed.
- Persistent cookies, which remain in the visitor’s computer until they are removed.

If you want to avoid cookies
To avoid cookies, your browser must be set to deny cookies or to ask each time a web site tries to place a cookie in your computer. In the web browser, you can also choose to erase the cookies generated up until that point, but it means your personal settings will be lost. See your web browser’s help pages for more information.
