Answer 1

会话 cookie 允许在网站内识别用户，因此您所做的任何页面更改或项目或数据选择都会逐页记住。此功能最常见的示例是任何电子商务网站的购物车功能。

会话 Cookie

    Webpages have no memories. A user going from page to page will be treated by the 
website as a completely new visitor. Session cookies enable the website you are visiting to 
keep track of your movement from page to page so you don't get asked for the same 
information you've already given to the site.

ASP.Net 中的会话 Cookie

    When a user connects to an ASP.NET application, a unique session ID will be affiliated 
with the user. If nothing is put in the session however, no cookie will be sent to the 
browser. This means that the user will get a new session ID the next time a new url is open or 
the page is refreshed. If something is put on the session (HttpContext.Current.Session["Hello] 
= "hello") however, ASP.NET will issue a cookie called ASP.NET_SessionId. This cookie contains 
the user's session ID and the cookie will expire at the end of the session (when you close 
your browser).

例如;

您访问 http://www.blablabla.com/message.aspx 并看到 请登录消息。

您登录该网站。之后，您将 http://www.blablabla.com/message.aspx 重写为您的浏览器，自动重定向您的消息框。

Session Cookies 就会发生这种情况。
