State management is the process by which you maintain state and page information over multiple requests for the same or different pages. As is true for any HTTP-based technology, Web Forms pages are stateless, which means that they do 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. Furthermore, pages are destroyed and re-created with each round trip to the server; therefore, page information will not exist beyond the life cycle of a single page. For more information about server round trips and the life cycle of Web Forms pages, see ASP.NET Page Life Cycle Overview.
