HttpRequest.IsAuthenticated Property

Gets a value indicating whether the request has been authenticated.

Namespace:  System.Web
Assembly:  System.Web (in System.Web.dll)

public bool IsAuthenticated { get; }

Property Value

Type: System.Boolean
true if the request is authenticated; otherwise, false.

The following code example uses the IsAuthenticated property to determine whether the current request has been authenticated. If it has not been authenticated, the request is redirected to another page where users can enter their credentials into the Web application. This is a common technique used in the default page for an application.

private void Page_Load(object sender, EventArgs e)
{
    // Check whether the current request has been
    // authenticated. If it has not, redirect the 
    // user to the Login.aspx page.
    if (!Request.IsAuthenticated)
    {
        Response.Redirect("Login.aspx");
    }
}
