c# - HttpWebResponse 发送到网络浏览器？

Question

我是 c# 的新手，正在制作一个简单的代理来编辑某些 header 。

我已经使用 HttpLisenter 获取请求，然后使用 HttpWebRequest 和 Response 进行编辑、发送和接收。

现在我需要一些帮助来将编辑后的响应发送回网络浏览器。有没有人有任何链接或例子？我很难过:)

谢谢

这是一个简短的例子:

public void ProcessRequest(HttpContext context)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create([NEW_URL]);
    request.Timeout = 1000 * 60 * 60;

    request.Method = context.Request.HttpMethod;

    if (request.Method.ToUpper() == "POST")
    {
        Stream sourceInputStream = context.Request.InputStream;
        Stream targetOutputStream = request.GetRequestStream();
        sourceInputStream.CopyTo(targetOutputStream);                
    }

    HttpWebResponse response = (HttpWebResponse)request.GetResponse();
    context.Response.ContentType = request.ContentType;

    using (response)
    {
        Stream targetInputStream = response.GetResponseStream();
        Stream sourceOutputStream = context.Response.OutputStream;
        targetInputStream.CopyTo(sourceOutputStream);                
    }
}

假设定义了以下扩展方法(我认为使用它可以使示例更具可读性):

public static void CopyTo(this Stream input, Stream output)
{
    using (input)
    using (output)
    {
        byte[] buffer = new byte[1024];
        for (int amountRead = input.Read(buffer, 0, buffer.Length); amountRead > 0; amountRead = input.Read(buffer, 0, buffer.Length))
        {
            output.Write(buffer, 0, amountRead);
        }                
    }
}
