【问题描述】:
正在测试的http文件示例: https://github.com/netty/netty/tree/4.1/example/src/main/java/io/netty/example/http/file
我用 netty-4.1.0.beta8 编译了上面的例子。
My test result:
$ ab -k -n 2 -c 1 -v 6 http://127.0.0.1:8080/test.sh

似乎我的 test.sh 内容被认为是第二个请求的标头。
我的进一步测试:

我对 www.google.com 运行了类似的命令,它运行良好。 你能帮忙吗?提前致谢。
【问题讨论】:
-
如果
-k被删除了还能用吗? -
是的。我的服务器在发送每个响应后关闭非保持活动 http 连接。在这种情况下,ApacheBench 知道它是套接字输入流的结尾。
