.NET CookieContainer帮助

我最近遇到了一些关于CookieContainer的问题。或者我做了一些严重错误的事情,或者有一些带有CookieContainer对象的bug。它似乎没有用特定的set cookie头更新cookie集合。

这可能是一篇冗长的文章,我对此进行了评估,但我希望尽可能地详细,所以我将列出我的HTTP嗅探日志以及实际的实现代码。

    public bool SendRequest(HttpWebRequest request, IDictionary<string, string> data, int retries)
    {
        // copy request in case request instance already failed
        HttpWebRequest newRequest = (HttpWebRequest)HttpWebRequest.Create(request.RequestUri);
        newRequest.Method = request.Method;

        // if POST data was provided, write it to the stream
        if (data != null && data.Count != 0)
        {
            StreamWriter writer = new StreamWriter(newRequest.GetRequestStream());
            writer.Write(createPostString(data));
            writer.Close();
        }

        // set request with global cookie container
        newRequest.CookieContainer = this.cookieJar;

        try
        {
            using (HttpWebResponse resp = (HttpWebResponse)newRequest.GetResponse())
            {
                //CookieCollection newCooks = getCookies(resp.Headers);
                //updateCookies(newCooks);
                this.cookieJar = newRequest.CookieContainer;
                this.Html = getResponseString(resp);

             /* remainder snipped */

所以这里有代码,这里有两个对我在fiddler中嗅到的响应的请求:

如您所见,用于每个请求的cookieContainer(this.cookiejar)没有为refer_id、cust_session、refer_id_persistent拾取set cookie头。不过,它确实会获取客户ID、私有浏览模式、TCC和成员会话…你知道为什么会这样吗?
