If you re familiar with HTML forms, you know there is one basic way to submit a page by clicking a submit button. If you re using the standard HTML server controls, this is still your only option. However, once the page is posted back, ASP .NET can fire other events at the same time (namely, events that indicate that the value in an input control has been changed). Clearly, this isn t enough to build a rich web form. Fortunately, ASP.NET web controls extend this model with an automatic postback feature. With this feature, input controls can fire different events, and your server-side code can respond immediately. For example, you can trigger a postback when the user clicks a check box, changes the selection in a list, or changes the text in a text box and then moves to another field. These events still aren t as fine-grained as events in a Windows application, but they are a significant step up from the submit button.

So, how do authentication, authorization, and impersonation all work together in a web application When users first come to your website, they are anonymous. In other words, your application doesn t know (and doesn t care) who they are. Unless you authenticate them, this is the way it stays. By default, anonymous users can access any ASP.NET web page. But when a user requests a web page that doesn t permit anonymous access, several steps take place (as shown in Figure 19-2): 1. The request is sent to the web server. Since the user identity is not known at this time, the user is asked to log in (using a custom web page or a browser-based login dialog box). The specific details of the login process depend on the type of authentication you re using. 2. The user provides their credentials, which are then verified, either by your application (in the case of forms authentication) or automatically by IIS (in the case of Windows authentication). 3. If the user credentials are legitimate, the user is granted access to the web page. If their credentials are not legitimate, then the user is prompted to log in again, or they are redirected to a web page with an access denied message.

Logging a user out of forms authentication is as simple as calling the FormsAuthentication.SignOut() method. You can create a logout button and add this code, as shown here: Protected Sub SignOutAction_Click(ByVal sender As Object, ByVal e As EventArgs) FormsAuthentication.SignOut() FormsAuthentication.RedirectToLoginPage() End Sub When you call the SignOut() method, you remove the authentication cookie. Depending on the application, you may want to redirect the user to another page when the user logs out. If the user requests another restricted page, the request will be redirected to the login page. You can also redirect to the login page immediately after calling the sign-out method. Or you can use the Response.Redirect method.

To use automatic postback, you simply need to set the AutoPostBack property of a web control to true (the default is false, which ensures optimum performance if you don t need to react to a change event) When you do, ASPNET uses the client-side abilities of JavaScript to bridge the gap between client-side and server-side code Here s how it works: if you create a web page that includes one or more web controls that are configured to use AutoPostBack, ASPNET adds a JavaScript function to the rendered HTML page named __doPostBack() When called, it triggers a postback, posting the page back to the web server with all the form information ASPNET also adds two hidden input fields that the __doPostBack() function uses to pass information back to the server.
