httping是一个用来测试 HTTP 请求的连接、发送请求、等待回应的时间。httping与ping类似，不过它不是发送ICMP请求，而是发送HTTP请求。利用httping，我们可以测量出Web服务器跟网络的延迟。

简单介绍一下几个常用的选项
-g 要测量的网址
-l 使用SSL连接
-c 这个和ping 一样，为请求数量
-Y 启用颜色输出
-x host:port(如果是测squid，用-x，不要用-h；和curl的不一样，curl -H指定的是发送的hostname，这个-h是指定给DNS解析的hostname)
-S 将时间分开成连接和传输两部分显示
-G GET(默认是HEAD)
-b 在使用了GET的前提下显示传输速度KB/s
-B 同-b，不过使用了压缩
-n a,b 提供给nagios监控用的，当平均响应时间>=a时，返回1；>=b，返回2；默认为0
-N c 提供给nagios监控用的，一切正常返回0，否则只要有失败的就返回c
-K 使用图形模式

httping还支持IPv6、代理、超时、请求头等其他特性，详情可以通过man httping查询。值得一提的是httping也有Android版本，有需要有朋友可通过Google Play获取。
