9，伪造来源地址，有的网站会判断，请求来源地址。
[root@krlcgcms01 mytest]# curl -e http://localhost //www.jb51.net/wp-login.php
[root@krlcgcms01 mytest]# curl -e http://localhost //www.jb51.net/wp-login.php
10，当我们经常用curl去搞人家东西的时候，人家会把你的IP给屏蔽掉的,这个时候,我们可以用代理
[root@krlcgcms01 mytest]# curl -x 24.10.28.84:32779 -o home.html //www.jb51.net
[root@krlcgcms01 mytest]# curl -x 24.10.28.84:32779 -o home.html //www.jb51.net
11，比较大的东西，我们可以分段下载
[root@krlcgcms01 mytest]# curl -r 0-100 -o img.part1 //www.jb51.net/wp-
