如何通过HttpWebRequest发送小写的Keep-Alive头 [英] How to send lower-case Keep-Alive header through HttpWebRequest

问题描述

我正在编写一个机器人，它应该尽可能地模拟firefox。
通过检查它发送的标题，我发现了一个小的区别，我不知道如何摆脱：

I'm writing a bot, which should emulate firefox as closely as possible. By examining the headers that it is sending, I've found one minor difference, that I do not know how to get rid off:

Firefox使用以下keep-alive header：

Firefox uses following keep-alive header:

Connection: keep-alive

虽然c＃总是发出：

Connection: Keep-Alive

我知道这可能没关系，但我仍然想知道是否有任何方法/ hack将该标题修改为全部小写。

I know that it probably does not matter, but I'd still love to know if there is any way/hack to modify that header to be all lower case.

任何想法如何做到这一点？

Any ideas how to do this?

推荐答案

在.net 4.0中，这有效：

In .net 4.0 this works:

request.Headers.GetType().InvokeMember(
    "ChangeInternal",
    BindingFlags.Instance | BindingFlags.NonPublic | BindingFlags.InvokeMethod,
    Type.DefaultBinder, 
    request.Headers, 
    new object[] { "Connection", "keep-alive" }
);

请确保您没有在请求中实际设置KeepAlive属性

Just be sure you don't actually set the KeepAlive property on the request
