阿帕奇板凳永葆得到0文件长度

Question

我用波纹管的命令： AB -k -n 1 -c 1 -v 5 $ URL 并获得：

LOG: header received: 
Blockquote 

HTTP/1.1 200 OK 

content-length: 228 

content-type: application/octet-stream

connection: keep-alive` 


LOG: Response code = 200

...

AB接收到的帧头：content-length: 228，但Document Length是0字节。 curl $ URL工作得很好，并获得228个字节。 那么它有什么问题？谢谢！

原来是ApacheBench的一个bug，它不接受低于内容长度的头文件。
