HttpWebRequest vs Fiddler using SSL

我有一个web应用程序使用HttpWebRequest发送一些数据到第三方服务。它是失败的，当我通过web代码运行它，但当我发送几乎完全相同的数据使用小提琴手的作曲家它的作品。

我说"几乎"是因为数据包含密码摘要、nonce和时间戳，每条消息都会更改。我已经设置了一个断点，并将web应用程序即将发送的数据粘贴到Fiddler中，它可以工作。

我已经设置了我的代码通过Fiddler的代理运行，这是伟大的-我可以看到"原始"数据被发送-它仍然失败，但它使我能够检查头都是完全相同的，混乱与他们一点(没有发现任何有用的)。

    WebProxy myproxy = new WebProxy("127.0.0.1:8889", false);
    req.Proxy = myproxy;

我已经禁用了Fiddler的"自动认证"answers"跟随重定向"选项(已经留下了"fix content-length header")，以防其中一个导致Fiddler行为智能。

这篇文章是一个https URL，所以我必须添加以下行来忽略Fiddler的证书问题时解密https流量

    ServicePointManager
        .ServerCertificateValidationCallback +=
        (sender, cert, chain, sslPolicyErrors) => true;

有人知道HttpWebRequest上的任何选项，我应该启用或禁用，使其作为提琴手吗?由于实际内容似乎相同，可能在安全性/身份验证选项上存在差异?

更改Fiddler的"解密HTTPS"设置似乎没有影响任何东西，除了意味着我无法查看数据。

会使用HttpWebRequest以外的东西是一个选项吗?还有哪些库不只是在底层使用HttpWebRequest ?我不需要异步，但HttpClient使用一个较新的库，处理事情更好吗?

我看过其他关于连接和使HttpWebRequest更高效的帖子，但目前我只是发布一条消息。

如果有帮助的话，下面是标题的样子:

消息体只是SOAP xml

下面是一些实现。net网络跟踪的数据

…然后有一些证书来回…

…更多的SOAP数据紧随其后(看起来像是加密的版本……．.. 加密的回复返回，然后它被解密…

…使用一些带有错误信息的XML(第三方似乎无法使用这些信息来查明问题)
