How can I take more control in ASP.NET?

I’m trying to build a very, very simple “micro-webapp” which I suspect will be of interest to a few Stack Overflow’rs if I ever get it done. I’m hosting it on my C# in Depth site, which is vanilla ASP.NET 3.5 (i.e. not MVC).

The flow is very simple:

If a user enters the app with a URL which doesn’t specify all the parameters (or if any of them are invalid)…

HTTP is a stateless protocol , session and viewstate help you to maintain states between request and response.

I am prepared to take the Pepsi challenge with this one.

"View state is simply text. It is an aggregate of values of controls on a page. It's a string that contains values of page controls hashed and encoded in some manner. The view state contains no information about the server or the client. It only comprises information about the page itself and its controls. It lives along with the page in the user's browser."

"Once again, view state is represented as a base64-encoded string. The keyword here is encoded. Not encrypted. Therefore if you were to decode it you would be able to gain insight of the workings of a web page. Maybe someone would be smart enough to store a credit card number in view state! This also means that someone may build their own page, pre-fill it and send it to your server (one-click attack) thus fooling it to believe it's dealing with a legitimate page. There's a simple yet effective way to counter this attack."
