Php的curl（模拟浏览器）访问另一台lamp架构测试80端口，哪个主动断开tcp连接

Php的curl（模拟浏览器）访问另一台lamp架构测试80端口，哪个主动断开tcp连接：

经测试，99.9%是httpd server服务器端主动断开，极少数是php的curl端主动断开。下面是centos7的lamp架构的测试文件，在另一台电脑上用ab命令访问进行测试，可以看到php的curl发送的请求，即远端为80端口的tcp连接只有ESTABLISHED状态。从curl的目标centos系统查看netstat –tan，则有很多80端口对应的TIME_WAIT状态。

[root@bogon ~]# netstat -tan |grep 80 #php curl发送端机器centos7 lamp架构机器
