为什么一定要保证proxyhost!=NULL

if(force_reload && proxyhost!=NULL)
  {
	  strcat(request,"Pragma: no-cache\r\n");
  }

if(clients==1) printf("1 client"); else printf("%d clients",clients);
在第188行左右，加这个判断的目的什么？直接printf不是也可以么。

This was the first project I studied, probably because of my limited ability, and I found that some places were not well understood. The following three points are some of my questions. Thank you for your guidance.

(1) Why isn't pid < 3 here? Is there any special meaning for pid being 2?

(2) Why does the bench() function return i? Isn't this the speed value that the parent process successfully read the last time? Could I change the program to return 0?

I think need a new variable here. Otherwise, It may hard to understand.

在install的时候提示没有webbench1这个文件，是不是将这个文件删除了，但是没有及时更新Makefile?

你好，我看了下代码，原理是不是就是通过fork()多个线程然后向http服务器发送请求，你是如何测试的，自己的服务器吗？

HTTP1.0定义了三种请求方法： GET, POST 和 HEAD方法。
HTTP1.1新增了五种请求方法：OPTIONS, PUT, DELETE, TRACE 和 CONNECT 方法。
而代码中仅仅提到了get head options trace,剩余的都没有涉及，是有什么特殊原因吗？

你好,为什么我debug,在benchcore方法里打了一个断点,为什么断点没有命中呢?如果换成printf打log确实是执行了的?
