No web application framework, no matter how advanced, can change the fact that HTTP is a stateless protocol. After every web request, the client disconnects from the server, and the ASP.NET engine discards the objects that were created for the page. This architecture ensures that web applications can scale up to serve thousands of simultaneous requests without running out of server memory. The drawback is that your code needs to use other techniques to store information between web requests and retrieve it when needed.
