Redirect different users to different web pages

This namespace required when the user logs in to the Web site and need to be authenticated for a valid or non-valid user.

 System.Web.UI.WebControls  

by using OnLoggedIn eventhandler we can rediect different users to different aspx page. 

 <asp:Login OnLoggedIn="EventHandler" />  
 <asp:Login ID="myLogin" runat="server" OnLoggedIn="Login_LoggedIn">  

For Example :

 protected void Login_LoggedIn(object sender, EventArgs e)  
   {  
     if (Roles.IsUserInRole(myLogin.UserName, "RoleOne"))  
     {  
       Response.Redirect("~/PageOne.aspx");  
     }  
     if (Roles.IsUserInRole(myLogin.UserName, "RoleTwo"))  
     {  
       Response.Redirect("~/PageTwo.aspx");  
     }  
     if (Roles.IsUserInRole(myLogin.UserName, "RoleThree"))  
     {  
       Response.Redirect("~/PageThree.aspx");  
     }  
   }
