请问apache中的keepalive可以在虚拟主机中使用吗？
官方上面简绍说可以，但是我在下面的配置中始终不成功。
源码安装2.2.9，
httpd.conf 这个文件只打开了httpd-vhosts.conf这行，其它的都没有变。
[root@localhost httpd-2.2.9]# grep httpd-vhost /usr/local/httpd/conf/httpd.conf
Include conf/extra/httpd-vhosts.conf
[root@localhost httpd-2.2.9]# tail -18 /usr/local/httpd/conf/extra/httpd-vhosts.conf
<VirtualHost *:80>
ServerAdmin webmaster@dummy-host2.example.com
DocumentRoot "/usr/local/httpd/htdocs"
ServerName huang2.huang.com
ErrorLog "logs/huang2-error_log"
CustomLog "logs/huang2-access_log" common
</VirtualHost>

<VirtualHost *:80>
ServerAdmin webmaster@dummy-host2.example.com
DocumentRoot "/usr/local/httpd/htdocs"
ServerName huang1.huang.com
ErrorLog "logs/huang1-error_log"
CustomLog "logs/huang1-access_log" common
KeepAlive On
KeepAliveTimeout 50
</VirtualHost>
在IE用访问huang1.huang.com连刷几次就得到下面的结果。

请问我上面是那里配置错误了吗？

1. KeepAlive 可以用於 vhost 內，請參考：

http://httpd.apache.org/docs/2.2/mod/core.html#keepalive

2. 我不知道你用 tcpdump 能看出啥重點，但是你應該使用 telnet 連結測試就知道。

測試連結後直接停在那邊，表示 google 支援 KeepAlive，所以一直等下一個動作。
