Fiddler和.Net 3.5 SSL错误.在.Net 4.0中运行良好

首先是站点和帖子。

https://saplic.receita.pb.gov.br/sintegra/SINf_ConsultaSintegra.jsp值为34151100004209的Fullfil Field CNPJ。

在Chrome和.Net 4.0 Httpwebrequest中运行良好。但我不能在fiddler中调试，也不能在.Net 3.5 上运行

我已经在使用了

System.Net.ServicePointManager.ServerCertificateValidationCallback += new System.Net.Security.RemoteCertificateValidationCallback(customXertificateValidation);
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Ssl3;
System.Net.ServicePointManager.Expect100Continue = false;

这简直把我逼疯了。任何帮助都将不胜感激为了让事情更清楚，我有一个问题发生在两个不同的地方（Fiddler和.net 3.5）

我试图运行的代码是.

    CookieContainer CookCon =  new CookieContainer();
    HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("http://sintegra.receita.pb.gov.br/sintegra/sintegra.asp?estado=pb");
    Request.Timeout = Configuration.TimeOut;
    Request.Proxy = Configuration.Proxy;
    Request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36";
    Request.Headers.Add("Accept-Encoding", "gzip, deflate");
    Request.CookieContainer = new CookieContainer();
    using (HttpWebResponse Response = Request.GetResponse() as HttpWebResponse)
    {
        foreach (Cookie C in Response.Cookies)
        {
            CookCon.Add(C);
        }
        Response.Close();
    }
    HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://saplic.receita.pb.gov.br/sintegra/");
    Request.Referer = "http://sintegra.receita.pb.gov.br/sintegra/sintegra.asp?estado=pb";
    Request.Headers.Add("X-DevTools-Emulate-Network-Conditions-Client-Id", "C5E5561B-11F5-4D9E-A9D4-54A18E660D11");
    Request.CookieContainer = CookCon;
    Request.Accept = "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8";
    Request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.103 Safari/537.36";
    string HTML = "";
    string Encoding = "ISO-8859-1";
    Request.Timeout = 20000;
    Request.Headers.Add("Accept-Encoding", "gzip, deflate");
    using (HttpWebResponse Response = Request.GetResponse() as HttpWebResponse)
    {
        Stream S = Response.GetResponseStream();
        if (Response.ContentEncoding.ToLower().Contains("gzip"))
        {
            S = new GZipStream(S, CompressionMode.Decompress);
            using (System.IO.StreamReader ResStream = new StreamReader(S, System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        else if (Response.ContentEncoding.ToLower().Contains("deflate"))
        {
            S = new DeflateStream(S, CompressionMode.Decompress);
            using (System.IO.StreamReader ResStream = new StreamReader(S, System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        else
        {
            using (System.IO.StreamReader ResStream = new StreamReader(Response.GetResponseStream(), System.Text.Encoding.GetEncoding(Encoding)))
            {
                HTML = ResStream.ReadToEnd();
                ResStream.Close();
            }
        }
        S.Close();
        S.Dispose();
        Response.Close();
    }

当我试图发布帖子时，我得到的错误是"未过期的EOF"（GetResponse是上面代码的一部分）。如果我试着在打开Fiddler的情况下在Chrome上冲浪，它不会向北返回，只是保持等待，等待，什么都不做。

如果我将相同的代码复制到一个新的4.0项目中，它就会毫无问题地运行。如果不清楚，请发布疑问，我会尽可能清楚。
