Back 13

The Cache object is stored in memory on the server.

Front 14

What types of data can you store in the Cache collection?

Back 14

You can store any type of data in the Cache collection. However, when you retrieve the data, you must cast it to the correct type.

Front 16

Which event would you handle to set the value of a Label control?

Back 16

Usually, you would handle the Page.Load event. Because other parts of a form probably do not rely on the value of a Label, you could also handle the Page.PreInit, Page.Init, or Page.Render event.

Front 17

What happens in the Init event of a page?

Back 17

Each child control of the page is initialized to its design-time value.

Front 18

How do ASP.NET web forms remember the settings for controls between user requests?

View state, which is enabled by default, is used to embed control property values to be sent to the client and back again to the server.

Front 19

Is the view state lost if a user refreshes a webpage? What if the user uses email to send a URL to a friend?

Back 19

View state is embedded inside the HTML of a single instance of a webpage displayed in the user's browser. It is lost and rewritten when a user refreshes his or her page. If the URL is copied and sent to another user, the view state does not go along. Instead, when new users request the page, they get their own view state instance.

Front 20

Which typically consumes more server memory: application state or session state?

Back 20

Session state tends to use much more memory than application state because application state is shared among users, whereas session state exists on a peruser basis.

Front 21

Which might not work if a user has disabled cookies in his or her web browser: application state or session state?

Back 21

Session state, by default, won't work if a web browser that supports cookies has cookies disabled. Application state is not user-specific, though, and does not need to be tracked in cookies. Therefore, application state works regardless of the cookies setting.
