This exercise will show you how to completely implement Forms authentication, from the web.con g to using the FormsAuthentication class. 1. Again, all authentications begin with configuring the web.config file accordingly. For Forms authentication, add the following to the web.config file: <configuration> <appSettings/> <connectionStrings/> <system.web> <compilation debug="true"/> <authentication mode="Forms"> <forms name=".ASPXFORMSAUTH" loginUrl="login.aspx" protection="All" timeout="30" path="/"> </forms> </authentication> <authorization> <deny users=" " /> </authorization> </system.web> </configuration> 2. Within your web project, you are going to add the following Web Forms: Login.aspx, Logout.aspx, and Home.aspx. After adding the Web Forms, right-click on the Home.aspx Web Form, and choose Set as Start Page. This sets the Home.aspx page as the default page within the application, and because you are not authenticated for access, you will be redirected to the login page speci ed within the web.con g. 3. Now that you have all the Web Forms set up, let s look speci cally at the Login.aspx Web Form. Add two textboxes and a command button to the Web Form. After adding these controls, double-click on the Command button to add an event handler to process the validating of the credentials.
