尝试设置代理但在浏览器

时间：2016-07-01 00:35:17

标签： asp.net iis proxy httpmodule

我正在创建一个自定义代理，该代理当前在我的本地计算机上设置以拦截CNN.com。我有成功点击我的代理的浏览器，请求被发送，我得到一个响应，它是200 OK响应完成与有效的HTML有效负载。我使用Wireshark来验证请求=＆gt; CNN和初始响应与我打开代理服务器和直接访问网站时的情况完全相同。

HttpWebRequest在发送之前看起来像这样：

但是，当我使用代理时，这就是所有Firefox报告收到的标题：

Date: Fri, 01 Jul 2016 00:11:44 GMT
Server: Microsoft-IIS/10.0
Transfer-Encoding: chunked

这导致我如何托管我的代理。它使用HttpModule通过IIS运行，并且该站点配置为在请求时运行所有托管模块。如何让浏览器接受此响应？

1 个答案:

答案 0 :(得分：0)

原来是Transfer-Encoding标题。我把它过滤掉了，它完美无缺。
