apacheBench 总是给出错误的非 2xx 响应：

Question

我使用 apache bench 已经有一段时间了，直到现在它工作得很好。然而，今天我开始得到几个Non-2xx responses:。为了进一步调查，我尝试运行用一个简单的网站进行测试，所以我运行:

ab -n 100 -c 10 http://www.yahoo.com/

这就是我得到的：

如输出所示，即使使用外部 url，我也会得到 100% 非 2xx 响应。有谁知道我该如何解决这个问题？

谢谢！

Answer 1

可能是因为在访问 Yahoo.com 时他们会重定向您，因此您会得到 30 倍的响应，而不是直接的 20 倍。
