ASP.NET State Management

ASP.NET State Management
A Web application is stateless. For example, by default if a user enters information into a text box on an HTML Web page, that information is sent to the server. However, it is not returned to the browser in the response. ASP.NET help you preserve data on both a per-page basis and an application-wide basis. These features are as follows:

1. View state
2. Control state
3. Hidden fields
4. Cookies
5. Query strings
6. Application state
7. Session state
8. Profile Properties

View state, control state, hidden fields, cookies, and query strings all involve storing data on the client in various ways.

Application state, session state, and profile properties all store data in memory on the server.
