A “cookie” is a small piece of information (token) sent by a Web server and stored on a user’s system (hard drive) so it can later be read back from that system. Using cookies is a convenient technique for having the browser remember some specific information.
Cookies may be categorized as “session” or “persistent” cookies. “Session” cookies are temporary cookies that are used to maintain context or “state” between otherwise stateless Web transactions and that must be deleted at the end of the web session in which they are created. “Persistent” cookies remain over time and can be used for a variety of purposes, including to track a user’s access over time and across Websites, or to establish user preferences. This Website does not use persistent cookies, i.e., tokens that pass information back and forth from your machine to the server and remain after you close your browser.
