Cookies not sent in WebBrowser? (C#, VS2008)

Question

Hi, I'm trying to add cookies to a webbrowser from a cookiecollection. I add them as they should be added but then they are not sent when the request is done. Here is the code I have done hitherto:

        public void myNav(string url, CookieCollection cc)
        {

            foreach (Cookie cook in cc)
            {
                webBrowser1.Document.Cookie = cook.ToString();
            }

            this.webBrowser1.Navigate(url);
            Clipboard.SetText(webBrowser1.Document.Cookie);
        }

If I copy the cookies to the clipboard they are sent correctly, but If I analyse the request with Wireshark they are not sent in the headers.

How can I solve this?

Thanks in advance, Ivan

@Sky Sanders That is what I tried, but it didn't work either.

    public void myNav(string url, CookieCollection cc)
    {

        if (this.webBrowser1.Document == null)
        {
            //No cookies in here
            MessageBox.Show("Document null -> Loading document");
            this.webBrowser1.Navigate(url);
        }
        while (this.webBrowser1.Document == null)
        {
            //Wait until document is not null
            Application.DoEvents();
        }

        foreach (Cookie cook in cc)
        {
            //Add cookies
            webBrowser1.Document.Cookie = cook.ToString();
        }

        //Navigate again
        this.webBrowser1.Navigate(url);
        Clipboard.SetText(webBrowser1.Document.Cookie);
    }
