这个信息叫做会话状态，是有用的应用程序的重要部分。
This information is called session state and is an important ingredient of a useful application.
此外，无状态很难实现，可能会导致多次往返数据库来获取本来通常存储在会话上下文中的信息。
Additionally, statelessness can be difficult to achieve and can lead to multiple round trips to the database for information that is normally stored within the context of the session.
我们可以通过将服务设计为在响应中包含合适的关联信息，从而避免会话状态的需求，例如以下的响应。
We can avoid the need for conversational state by designing the service to include suitable correlation information in the response, such as the following.

有状态会话bean保存特定客户机调用之间的信息。
A stateful bean preserves information between invocations from a specific client.
如果不能识别，服务器可以忽略全部或部分Header(比如，无状态的服务器可能会忽略Header中的会话信息)。
The server is free to ignore all or some of the header if it does not recognize it (for instance, a stateless server may ignore session information from the header).
StoreControllerservlet使用称为CategoriesBean的无状态会话EJB 的getCats()方法获取产品类别信息。
The StoreController servlet fetches the product categories information using the getCats() method of a stateless session EJB called CategoriesBean.
ErrorBean实例被存储在用户的会话中（关于会话的更多信息，请参阅JeffWilson 的文章，GoFor-It 记事，第 3部分：会话管理，servlet和维护状态）。
The ErrorBean instance is stored in the user's session (for more about sessions, see Jeff Wilson's article, The GoFor-It Chronicles Part 3: Session management, servlets, and maintaining state).
会话状态的目的是保持那些临时性的且无法从其他状态或当前交互重新计算的信息(例如，购物车的内容)。
The purpose of session state is to keep information that is transient in nature and that cannot be recomputed from other state or the current interaction (for example, the content of a shopping cart).
使用会话状态的目的是为了保存不能从另一个状态或当前交互重新计算的瞬时信息。
The purpose of session state is to keep information that is transient in nature and that cannot be recomputed from another state or the current interaction.

A Screen session is running (albeit unseen), and window a is active, running the top system monitor, which refreshes system performance information every few seconds.
在并行重组过程中，采用二维链表保存（例如会话列表、相应状态和任务分配结果等）关键信息。
Some key information such as sessions and their corresponding states, operation results were saved by using a two-dimensional linked list in parallel reassembly process.
NET提供状态管理功能，以便您可以在往返行程间保存您自己的变量和应用程序特定或会话特定的信息。
NET provides state management capabilities so you can save your own variables and application-specific or session-specific information between round trips.
