COOKIES是什麼?為什麼沒有它便看不到e-mail?

HTTP cookies, sometimes known as web cookies or just cookies, are parcels of text sent by a server to a web browser and then sent back unchanged by the browser each time it accesses that server. HTTP cookies are used for authenticating, tracking, and maintaining specific information about users, such as site preferences and the contents of their electronic shopping carts. The term "cookie" is derived from "magic cookie," a well-known concept in Unix computing which inspired both the idea and the name of HTTP cookies.

Cookie，有时也用其复数形式Cookies，指某些网站为了辨别用户身份而储存在用户本地终端上的数据（通常经过加密）。定義於RFC2109。它是网景公司的前雇员Lou Montulli在1993年3月的發明。

用途
服务器可以利用Cookies包含信息的任意性来筛选并经常性维护这些信息，以判断在HTTP传输中的状态。Cookies最典型的应用是判定注册用户是否已经登录网站，用户可能会得到提示，是否在下一次进入此网站时保留用户信息以便简化登录手续，这些都是Cookies的功用。另一个重要应用场合是“购物车”之类处理。用户可能会在一段时间内在同一家网站的不同页面中选择不同的商品，这些信息都会写入Cookies，以便在最后付款时提取信息。
