I'm sure you're familiar with the traditional interface model for a web application. The user requests a page from the server, which is built and delivered to the browser. This page includes an HTML form element for capturing data from the user. Once the user posts their input back to the server, the next page can be built and served based on the input, and so the process continues. This is largely dictated by the nature of HTTP and differs from the traditional desktop application model of an interface which is inherently connected to the application layer. Take the simple example of filling out a serial number box to register a desktop app on a platform like Microsoft Windows.
