I set some node to request role based access credential, and I built a login page to accompany with the settings.

My question is if login fails is there a way I can simply throw 401 code from that login page I built without displaying anything or use setting in web.config <forms name="yourAuthCookie" loginUrl="login.aspx" protection="All" path="/" />

Currently if my code in my login page is

if (this.Authenticate(username, password))
{
    Response.Redirect(contentPageUrl, false);
}
else
{
    Response.StatusCode = 401;
    Response.End();
}
private bool Authenticate(string username, string password)
{
    if (Membership.ValidateUser(username, password))
    {
        FormsAuthentication.SetAuthCookie(username, false);
        return true;
    }

    return false;
}

Then Umbraco tries to use /login.aspx as set in config file

Or if my code is

if (this.Authenticate(username, password))
{
    Response.Redirect(contentPageUrl, false);
}

It just show the same custom login page again.
