web-services - 通过具有 NTLM 授权的代理请求具有基本授权的 Web 服务不起作用

Question

我有一个需要基本授权的 Web 服务和一个需要 NTLM 授权的 Internet 代理背后的用户。我还有一个表单应用程序，它调用 Web 服务并要求用户提供 Web 服务凭据(与 NTLM 凭据不同)。

我让应用程序配置工作(WCF ServiceModel)，它使用默认代理凭据，请求正在使用代理进行身份验证，但是在使用 Web 服务进行身份验证后，由于某种原因它不会发送请求正文。

如果我在没有 NTLM 代理的情况下进行本地测试，则该过程有效。抱歉，示例太长，但我必须将它们包括在内。

第一个请求:

我不明白为什么它不在第四个请求中发送信封。两次握手都完成了，所以理论上一切都应该没问题。

当我在没有 NTLM 代理的情况下在本地执行此操作时，信封会按预期发送:

Answer 1

我不得不更改服务器安全配置以接受摘要式身份验证。出于某种原因，Basic 不起作用。
