ASP.NET Session State Overview
ASP.NET session state enables you to store and retrieve values for a user as the user navigates ASP.NET pages in a Web application. HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests. ASP.NET session state identifies requests from the same browser during a limited time window as a session, and provides a way to persist variable values for the duration of that session. By default, ASP.NET session state is enabled for all ASP.NET applications.
Alternatives to session state include the following:
Application state, which stores variables that can be accessed by all users of an ASP.NET application.
Profile properties, which persists user values in a data store without expiring them.
ASP.NET caching, which stores values in memory that is available to all ASP.NET applications.
View state, which persists values in a page.
Cookies.
The query string and fields on an HTML form that are available from an HTTP request.
