测试:[root@www ~]# curl -x127.0.0.1:80 www.test.com/forum.php(会提示<title>403 Forbidden</title>)

[root@www ~]# curl -x127.0.0.1:80 www.test.com/adkljh(也是403)

[root@www ~]# curl -x192.168.137.2:80 www.test.com/asdfg(也是403)

现在把curl那行注释,[root@www ~]# curl -x192.168.137.2:80 www.test.com/asdfg(会提示404)

[root@www ~]# curl -x192.168.137.2:80 www.test.com/forum.php -I(会提示200)
