How to check if browser cookies are allowed in a web application?

I decided to rewrite the question because I found some information on how to accomplish the above: http://msdn.microsoft.com/en-us/library/aa289495%28v=vs.71%29.aspx

However, my problem is that I am trying to do all this in an event Page_Load Login.aspx.cs.

At first it works fine until I try to log in by entering my credentials and clicking the "Login" button. Then all the infernal breaks are lost and I get an endless loop. It continues to navigate between download pages on Login.aspx.csand TestForCookies.aspx.cs. Every time a redirect URL grows with another one "?AcceptCookies=1. "Is there any work for this?

Code Login.aspx.cs:

protected void Page_Load(object sender, EventArgs e)
{
    if (!Page.IsPostBack)
    {
        if (Request.QueryString["AcceptsCookies"] == null)
        {
            Response.Cookies["TestCookie"].Value = "ok";
            Response.Cookies["TestCookie"].Expires = DateTime.Now.AddMinutes(1);
            Response.Redirect(BasePage.ResolveUrl("~/Common/TestForCookies.aspx?redirect=" + Server.UrlEncode(Request.Url.ToString())));
        }
        else
        {
            LoginBox.InstructionText = "Accept cookies = " + Request.QueryString["AcceptsCookies"];
        }
    }

}

Code TestForCookies.aspx.cs:

protected void Page_Load(object sender, EventArgs e)
{
    string redirect = Request.QueryString["redirect"];

    string acceptsCookies = null;
    // Was the cookie accepted?
    if (Request.Cookies["TestCookie"] == null)
    {
        // No cookie, so it must not have been accepted
        acceptsCookies = "0";
    }
    else
    {
        acceptsCookies = "1";
        // Delete test cookie
        Response.Cookies["TestCookie"].Expires = DateTime.Now.AddDays(-1);
    }

    string url = redirect + "?AcceptsCookies=" + acceptsCookies;


    Response.Redirect(url);
}
