HttpContext.User Problems.

I'm having a problem with the HttpContext.User property. I notice this property has an Identity object with an IsAuthenticated property. All of this is ReadOnly though. At what point do I ever get the opportunity to set these values?

I am avoiding the default MembershipProvider model of ASP.NET 2.0 for multiple reasons, and even if I did persue it, I don't see how these values are set. I want to check the User.Identity.IsAuthenticated property during an HttpModule, and the IsAuthenticated needs to be true or false based on whether the user is properly logged in (using custom forms authentication).

in order for the HttpContext.User to be set, the ControlPrincipal flag will HAVE to be set
here is some examples on msdn

I don't understand. all it shows is how to make objects with those flags, not actually how to set them....

(this is not how the final code will work, it's just a test)
Following the example, I'm applying the flag to a method and it won't let me compile, it says it is still readonly..

        ''' <summary>
        ''' Authenticates the calling http request and validates the member.
        ''' </summary>
        ''' <param name="sender"></param>
            ''' <param name="e"></param>
            <SecurityPermissionAttribute(SecurityAction.RequestOptional, ControlPrincipal:=True)> _
  Public Sub AuthenticateRequest(ByVal sender As Object, ByVal e As EventArgs)
                  HttpContext.Current.User.Identity.IsAuthenticated = True
            End Sub

I think I've figured it out. It's a little awkward, how Microsoft chose to implement this system, though. Thank you very much for the flags help.

Hrnm, Actually I am still confused.

I've figured out I can use FormsAuthentication.SetAuthCookie to set the Identity in the User control. . but it doesn't seem to work as intended..

            FormsAuthentication.SetAuthCookie(Me.UserName.Text, True)
            FormsAuthentication.RedirectFromLoginPage(Context.User.Identity.Name, True)

Doesn't seem to pass the username properly.. Yet it should control the IPrincipal Object, Right?

yes that is correct.
when  you say it doesnt work as intended, what do you mean? what do you expect to see and what actually happens?
