curl命令及返回
基本指标
curl URL #获取该网址的文本信息
-i URL #获取该网址的文本信息以及协议头部信息
-x 47.94.151.148:80 zhujy.com.cn #使用代理获取网页文本信息
-I url #仅返回请求头部信息
-C/–continue-at # 断点续转
-v #参数可以显示一次http通信的整个过程，包括端口连接和http request头信息
-V #show the version of curl
常用命令
curl -O http://10.167.209.1:1212/hongtabank/ #下载指定ip底下的hongtabank文件
curl www.zhujy.com #获取该网址的文本信息
这就是获取的www.zhujy.com信息

很多时候所谓的http的请求、响应的模式，都是客户端加载一个网页，直到用户在进行下一次点击的时候，什么都不会发生。并且所有的http的通信都是客户端控制的，这时候就需要用户的互动或定期轮训的，以便从服务器端加载新的数据。
通常采用的技术比如推送和comet（使用http长连接、无需安装浏览器安装插件的两种方式：基于ajax的长</div>
