Web Forms State Management

Visual Studio .NET 2003

Web Forms pages and the ASP.NET page framework use HTTP to communicate between browser or client device and the Web server. HTTP is a stateless protocol, meaning that it does not automatically indicate whether the requests in a sequence are all from the same client or even whether a single browser instance is still actively viewing a page or site. In addition, each time a page is processed in a round trip, it is destroyed and rendered anew, and all information about the state of the Web Forms page and the controls on that page are lost.

As a result, building Web applications that need to maintain cross-request state information — for example, showing a shopping cart or paging through data — can be extremely challenging without additional infrastructure help.

The following topics provide a general background and how-to information on how you can manage state in your Web Forms pages.
