推荐答案

虽然自身被存储在服务器上（或在SQL如果配置这样）中的数据，需要有与特定用户会话数据相关联的方法

Whilst the data its self is stored on the server (or in SQL if configured that way), there needs to be a way to associate session data with specific users.

默认情况下它是用饼干做的，但您可以配置在这种情况下，唯一的ID被存储在URL中Cookie的。

By default this is done with a cookie, but you can configure cookieless in which case the unique id is stored in the URL.

从微软：

ASP通过提供客户端，与会话开始时分配给该用户的唯一密钥保持会话状态。这个密钥存储在客户端发送到每个请求的服务器的HTTP Cookie中。然后，服务器可以从cookie读取密钥并重新膨胀服务器会话状态。

ASP maintains session state by providing the client with a unique key assigned to the user when the session begins. This key is stored in an HTTP cookie that the client sends to the server on each request. The server can then read the key from the cookie and re-inflate the server session state.
