Cookie
The most common meaning of
`Cookie` on the Internet refers to a piece of information sent by a
Web Server to a Web Browser that the Browser software is expected to
save and to send back to the Server whenever the browser makes
additional requests from the Server. Depending on the type of Cookie
used, and the Browser`s settings, the Browser may accept or not
accept the Cookie, and may save the Cookie for either a short time
or a long time. Cookies might contain information such as login or
registration information, online `shopping cart` information, user
preferences, etc. When a Server receives a request from a Browser
that includes a Cookie, the Server is able to use the information
stored in the Cookie. For example, the Server might customize what
is sent back to the user, or keep a log of particular user`s
requests.
