HTTP Module - ASP.NET 2.0 Membership

[Guest]

I am trying to create an HTTP module to run on ASP.NET 2.0. The module needs
to check to see if the user is authenticated with the .net 2.0 membership
stuff. I am trying this:

If application.Context.User.Identity.IsAuthenticated Then
app.Context.Response.Write("user authenticated")
End If

I am always getting an error. Does anyone have any suggestions? Do I need
to configure anything special for the module? Thanks.
