Question

我正在尝试与服务器建立连接，该服务器为所有请求发送401身份验证错误以及正常的html响应。例如但是，我还想阅读随之发送的HTML响应，以便我可以解析它。使用LiveHTTPHeaders捕获的示例标头交换：显然，内容长度不为零。 Firefox将其显示为javascript。

https://172.31.1.251:1003/fgtauth?73e285357b2dc5cc
Request:

Response:

WWW-Authenticate: Fortigate

此时，在Firefox中打开一个表单，要求我输入我的用户名和密码。

https://172.31.1.251:1003/

Response:
HTTP/1.x 401 Unauthorized
WWW-Authenticate: Fortigate
Content-Length: 924
Connection: Keep-Alive
Cache-Control: no-cache

此时我被重定向到另一个URL。但是，我遇到的问题是如何获取与401 Unauthorized一起发送的长度924的内容，因为该内容将帮助我做我想做的事情。但是这一行：

WebResponse loginResponse = loginRequest.GetResponse();

抛出异常。

如果有任何建议可以帮助我了解实际内容，我将不胜感激。

感谢。
