引用：

应用程序和会话状态有一个非常重要的区别：



应用程序状态是ASP.NET应用程序中所有类都可用的数据存储库。应用程序状态存储在服务器的内存中，比在数据库中存储和检索信息更快。与会话状态（特定于单个用户会话）不同，应用程序状态适用于所有用户和会话。因此，应用程序状态是存储少量常用数据的有用位置，这些数据不会从一个用户更改为另一个用户

另一方面，缓存允许您将对象存储在需要大量服务器资源来创建的内存中 - 它提供了强大的功能，允许您自定义项目的缓存方式以及缓存时间 - 您可以设置广泛的属性，如优先级和到期时间。

虽然它们可能看起来很相似，但它们明显是分开的，并且在最广泛的意义上在ASP.NET应用程序中扮演不同的角色。

Application and Session State have a very important difference:

Application state is a data repository available to all classes in an ASP.NET application. Application state is stored in memory on the server and is faster than storing and retrieving information in a database. Unlike session state, which is specific to a single user session, application state applies to all users and sessions. Therefore, application state is a useful place to store small amounts of often-used data that does not change from one user to another

Caching, on the other hand, allows you to store objects in memory that require extensive server resources to create - it offers powerful features that allow you to customize how items are cached and how long they are cached - you can set extensive properties like priority and expiration.

Although they might appear similar, they are distinctly separate and have different roles to play in an ASP.NET application in its broadest sense.
