我们需要发送超过 16181 个字符的获取请求。此时我们最多可以发送：15,861 之后我们得到：

HTTP 错误 400。请求标头的大小太长。

这是在注册表中配置为 DWORD 值的内容：

MaxFieldLength: 65534 
MaxRequestBytes: 16777216 
UrlSegmentMaxLength: 32766

在 IIS 中：

maximum allowed content length 2147483647
maximum url length 2147483647
maximum url length 2147483647

网络配置：

  <requestFiltering>
    <requestLimits maxAllowedContentLength="2147483647" maxUrl="2147483647" maxQueryString="2147483647" />
  </requestFiltering>

在 HTTPERR 我得到：

2020-02-17 17:31:01 172.16.144.50 59371 172.16.144.50 80 HTTP/1.1 GET LONGURL- 400 - RequestLength -

日志削减了部分 url。

我错过了什么？
