Yahoo BBAuthen with authentication session? - yahoo

Question

I'm trying to use yahoo BBA with my web application, but I'm always get fail with yahoo authentication problem.
Here is my odd code:
YahooLogin.aspx.cs
protected void ImageButtonYahoo_Click(object sender, ImageClickEventArgs e)
{
// Create an instance of Yahoo.Authentication
Yahoo.Authentication auth = new Authentication(strApplicationID, strSecret);
// Redirect the user to the use sign-in page
Response.Redirect(auth.GetUserLogOnAddress().ToString());
}
And end-point url: BBAuth.cs
protected void Page_Load(object sender, EventArgs e)
{
bool success = false;
// Retrieve this user's authentication object we've stored in the session state
Yahoo.Authentication auth = Session["Auth"] as Yahoo.Authentication;
if (auth == null)
{
// We have a problem with the current session, abandon and retry
Session.Abandon();
Response.Redirect("ErrorPage.aspx");
}
// Check if we are returning from login
if (Request.QueryString["token"] != null && Request.QueryString["token"].Length > 0)
{
// Make sure the call is valid
if (auth.IsValidSignedUrl(Request.Url) == true)
{
success = true;
// Save the user token. It is valid for two weeks
auth.Token = Request.QueryString["token"];
}
}
// Redirect if we succeeded
if (success == true)
{
Response.Redirect("Default.aspx");
}
else
{
Response.Redirect("SignInError.aspx");
}
}
Response.Redirect("ErrorPage.aspx"); always execute, someone can tell me what is missing in my code.
Thanks,
